Great Sketching Book for Children

 I wrote the following review of Jean Mackay's The Nature Explorer's Sketchbook: For the Art of Your Discoveries, for a local weekly. It never was published, so I'm running it here.



Front Cover


Want to introduce children to the natural world, or just get them away from their digital toys? Jean Mackay’s The Nature Explorer’s Sketchbook is a great start. The book combines instruction with an enthusiastic invitation to get involved with nature. Artist-author Mackay writes on the very first page, “The world is a Big and fascinating place. Let’s go out and explore it.”

 

The firsts 25 pages of the book introduce the reader to nature journaling, with plenty of specific sketching ideas along with very basic drawing and painting instructions.

 

With roughly 55 blank pages following, the book is designed for immediate action, making it easy to jump from reading to doing. Some of the blank pages are subdivided into smaller squares and rectangles - a subtle way of introducing children to page design. The stretch of blank pages is broken up with “Try This” ideas, which keeps interest and enthusiasm from flagging.

 

From the initial “This Book Belongs To “___” to the last page, the book actually becomes the child’s work as much as the author’s. In fact, Mackay stresses, “You make your own rules - it's your book."  As for feeling discouraged, her advice is practical, “If you draw something you don’t like, just turn the page and try again.” In this way Mackay motivates the reader to keep going, and when it is finished the child will have a real sense of accomplishment along with a personal record of discoveries and experiences.



Artwork By Jean Maccay



Jean Mackay incorporates language with her own sketches, and writing is as important as drawing in this book. Combining writing with drawing helps establish a deep connection between the observer and world being observed.  She writes, “The more you sketch the more you will see.” That is true of writing as well. 

 

She doesn’t stop with generalities, but gives specific tips like noting sensations, the weather and how the sketcher feels. One exercise is to fill a space entirely of words written large or small, decorated or not, to describe the sense of a place. 

 

She also encourages the reader to write down questions about what is being sketched, looking up information later, and adding answers. Some questions about a plant, for example, could be whether it is edible, what the various parts are called, why it is growing where it is, and so forth.

 

In content and organization this childrens’ book does not differ materially from similar books for adults. The difference lies in the amount of detail about techniques and materials.  While just a little more information on materials and techniques might have been welcome here, the author clearly wants to get children involved and excited immediately. In view of this goal, less is likely better. 

 

Mackay mentions that a heavier paper than what is in the book would be better for watercolor. I tried a small, wet sketch. While the paper buckled, it didn’t start to disintegrate or tear, and it dried fairly flat. As long as the user doesn’t go hog wild with water or scrubbing, the paper in the book should be fine for starters. 

 

The current emphasis on the STEM curriculum – science, technology, engineering and mathematics – raises the question of whether the creative arts will be neglected or ignored in the education of young people. A book like The Nature Explorer’s Sketchbook shows how language and art can go hand-in glove with these categories.  The subtitle, For the Art of Your Discoveries, says it all. 

 

The book is enlivened with Mackay’s delightfully fresh and energetic sketches, mostly done in watercolor. While this kind of seemingly loose and spontaneous style actually takes years to perfect, it is not intimidating, and perfectly suited to her topic and audience. She does not talk down to her audience, and constantly seeks to encourage and inspire.




Back Cover


Older teenagers might find this book too juvenile, but curiously enough, it probably would appeal to busy grownups for the same reasons it would please children. If you buy this book for your offspring, you may end up wishing you had a copy for yourself. The book would be a wonderful resource for teachers, day camps, and whole-family activities.  

 

The book is published by Tumblehome Press, a non-profit childrens’ book publishing company that aims “to inspire a love of science through the power of story.”

 

It is a sturdy paperback, 10 x 7 inches large, and has good –quality binding, that should withstand a good deal of abuse. Considering the cost of books and decent drawing paper, this little manual is very reasonable at $16.99. It’s release date was Nov. 1, 2020. It is perfect for summer vacation activities and gifts.

Signs of Spring

Just a few days ago I heard the familiar lament, "I like Florida, but I really miss the change of seasons." We don't have jonquils and crocus, but  there are plenty of signs heralding the advent of spring in SW Florida. As for color signals, what more do you need than the show put on by flowering trees - deep yellow Tabebuia,cooling lavender Jacaranda, delicate pink masses of flowering almond - just to name a few.  

The trees named above aren't native to Florida, but so much goes on in March in the natural world that I labeled 2 posts "March Madness" in 2017. This year has been a little crazy apart from the garden, and  I have made many more scribbled notes than sketches. I hope to catch up on some of the later spring manifestations.

The return of the swallow-tailed kites is a sure sign that the winter has turned. I spotted my first one of this year in the second week of March. These striking white-and- black-marked raptors demonstrate how little color has to do with real beauty. No matter how many I've seen, a soaring swallow-tailed kite still takes my breath away. Author and artist David Allen Sibley talks of their,"unmistakeable; incredibly graceful, flowing flight."(The Sibley Guide to Birds, p. 111). The birds don't use just their tail feathers for maneuvering, but also can twist their entire lower body to execute their aerial acrobatics.

Swallow-tailed kites nest in tall trees in hardwood forests, and due to development, especially intense timbering and replacement of mixed forests with pine plantations, their range in the U.S. has shrunk drastically. They used to nest as far north as Minnesota. Now they are limited to peninsular Florida, and the coasts of Georgia, South Carolina, Alabama, Mississippi, and eastern Louisiana. They return to South America in the fall. 

They pluck their prey - reptiles, amphibians, insects and small birds from the treetops or catch and eat them in flight. I haven't read that they do so, but I wouldn't be surprised to find that they also rob nests of other species. Perhaps that is calumny, but "Mother Nature" isn't kind, and she doesn't always go by the rules.

Frangipani, Plumeria sp., isn't native to Florida, but it consumes few, if any, resources, and isn't invasive. It is a quintessential "pass-along" plant. I got mine from a sister, who got hers from a friend. All you have to do to grow it is stick a branch into the dirt, water a little, and watch it grow. Once it is established it needs no irrigation or fertilizer. (At least the one in our yard behaves that way). There are many species and varieties, but the only two I see around the neighborhood are a  pink-flowered and a yellow-flowered one. Ours is  yellow-flowered, and fragrant. Frangipani is one of the flowers traditionally used in Hawaiin leis.



Frangipani Flower Cluster




Once the weather is good and dry, frangipanis lose all their leaves, and look completely dead and more than slightly creepy - like some sort of alien life form, which is just waiting to emerge and wreak havoc. 




Dormant Frangipani Branch



I used a variety of colored pencils to capture the gray-green, turgid look of these branchlets, which really do resemble dead fingers. The true color is something in between all my attempts. The large dry markings are leaf scars from previous seasons, and the squiggly maroonish things at the very tip are nascent leaves. New growth literally bursts through the skin. Buds and stems don't magically appear on the branches, but rupture the skin, leaving oozing wounds. 

Last month, bloom stalks capped with numerous flower buds started rising from the branch tips, and now the first flowers have opened. The plant is a member of the Dogbane Family, and all parts, including the white sap, are somewhat poisonous. I haven't found the sap irritating, but I haven't gotten much on my skin, and other people might have a reaction to it.


Emerging Flower Stalk
Maroon Structures are Young Leaves



The Great Southern White and Florida White butterflies reappear in mid-to-late March. Both occur here about the same time, and I'm not quick enough to id them on the fly. When we first moved here in 1994, we would see great swarms of white butterflies, but now we see them singly or maybe in pairs. If you can get close enough to see them, the bright turquoise tips on the antennae are a dead giveaway for the Great Southern White.


White Butterflies:
Great Southern White, Left, and Florida White, Right



The emergence of lubber grasshopper nymphs is also a marker for spring. The nymphs start emerging in great numbers in February. So far they have defoliated one bougainvillea, and demolished the Crinums and Tradescantias. They'll all recover, with the possible exception of the Tradescantia. which really are happier in more northern sections of Florida. There must be many microorganisms that afflict the nymphs, because the number of adults I see later on is a fraction of the immature population. Both nymphs and adults allegedly are toxic to most predators. 

Newly-Emerged Lubber Nymphs



Just like "up north," perennials are forming new basal rosettes and resuming growth. Elephant's foot and rosinweed have made a fine beginning, while blackroot and Pluchea have resprouted directly.  Native grasses like Elliott's Love Grass and Pink Muhley are sending out fresh, colored blades from what clumps of dried foliage from last year. Gaillardias sown by last year's plants are germinating here and there in the yard. I leave them where they don't block a path, and try to transplant others, even though it sets them back. 

March brings persistent drying winds. Our last rain was the second week in February, and given the wind and increasing sunshine I have to water at least twice a week now, whereas during winter even the potted plants don't require a lot of attention. 



Blue-Eyed Grass



Blue-eyed grass made a magnificent display throughout late winter and early spring, but is going to seed now. The tickseed is also beginning to appear somewhat the worse for wear.

It's March Madness in the garden all over again. There is plenty more going on, but I have to stop for now.

January - Not the Greatest New Year

January came and went, and for once, time seemed to drag. Apart from political and COVID misery, the month opened with gray, chilly weather, powdery mildew, and an episode of red tide. Not a great start for a happy new year. 

 Powdery mildew first appears as white, somewhat circular splotches on the top sides of leaves. It looks a little like they have been sprinkled with flour or talc. Yellowing, browning, and death of the leaf may follow.  Powdery mildew, a true fungus, flourishes with  cool nights combined with high humidity and warm days. This time of year we tend to have heavy dewfall, and even fog. If I were growing vegetables this year, I most likely also would be dealing with downy mildew, a socalled "water mold," which likes the same conditions. 

Since crowding, combined with shade and moisture, makes powdery mildew worse, it showed up mainly on large clumps of dune sunflower, Helianthus debilis growing around  some palms and  large shrubs in the front yard, and on the near-prostrate rosettes of Elliott's aster.

I am letting the Elliott's aster deal with the mildew on its own. The rosettes collect moisture every night and early morning. I probably couldn't get it completely eradicated even with a regular spray schedule, and since I avoid pesticides, I'm not spraying it at all. Since this is a recurring event, I expect the asters to grow out of the problem once the drying winds and sunnier days of March roll in.



Powdery Mildew on Elliott's Aster


I pretty much got rid of the mildew on the dune sunflowers by drastic pruning, even removal of entire clumps.

 Left to itself in a garden situation, dune sunflower forms large, mounding clumps, often with dead, decaying, or whitefly-infested branches hidden underneath. Keeping them nice and somewhat contained requires periodic pruning, even cutting back to the ground. The ones I removed didn't have these problems yet. Salt spray and wind keep the plants smaller in their dune habitat. 

The back yard is subject to pitiless sun most of the day,  so powdery mildew rarely pops up there. It was time to do hard pruning of the sunflowers there anyway, just to tidy things up, and remove dead branches. I like to leave "islands" of it so that what snakes and reptiles we still have can move around with some cover. The great egret in particular is a voracious predator of anoles and skinks, and I once saw a hawk pluck a corn snake from the front yard. 

There are 3 subspecies of Helianthus debilis in Florida. My plants, originally obtained from native plant sales, are predominantly the east coast dune sunflower, Helianthus debilis subsp. debilis. The species hasn't been vouchered in Collier County, but I have seen it growing on the dunes. Since walking on the dunes is a serious no-no because it is so destructive,  I can't say for sure what subspecies they are. The plants in our yard are both mounding and somewhat vining. They root easily at the nodes. The leaves are roughly triangular, and shaped like arrowheads with a large base. They have a sandpapery texture. The petioles are long, and the leaf margins vary from entire to noticeably toothed. The stems range in color from green to maroon, and are also somewhat rough to the touch. The sinuous quality of the stems makes the plant fun to draw. 



Helianthus debilis Stem with Opening Head


Flower heads are an intense yellow. Just before the sun sets, they can take on a slightly luminous quality.  The plants are evergreen here, and bloom all year. Butterflies and moths visit them, though they are not favorite nectar  plants. A variety of bees, wasps, and other small pollinators are more common visitors in our yard. Mourning doves like to shelter under them, and no doubt eat the seeds.



Dune Sunflower Habit


Apart from its eagerness to overrun the entire yard, Helianthus debilis is a great garden plant. Its colorful blooms and  bright foliage enliven the yard. Like Gaillardia, a clump of dune sunflower just cheers up the scene. Its semi-vining stems will cascade prettily over the sides of a large pot. The hidden branches of a large, old clump become infested with whitefly and mealy bugs over time. Otherwise I haven't noticed any insect problems, and no disease troubles other than the seasonal mildew. The plant is extremely drought tolerant. I never water it unless it is in a pot.

-----------------------

Officials like to say that red tide is a natural phenomenon. They're right - to an extent. These algal blooms can be caused by an upwelling of nutrients from the ocean floor, triggered by large storms, temperature swings, changes in salinity, and so forth. They normally occur here when the weather is warm - from August to November. 

But red tides have become more persistent in the past 5 or so years, exacerbated by humans. The period from the summer of 2016 through the winter of 2019 was particularly disastrous for southern Florida. Heavy rains forced the Army Corps of Engineers to make record-breaking discharages of fresh water from Lake Okeechobee. The fact that the earthen levee around Okeechobee is obsolete and can't stand the pressure of elevated water levels has been known for decades, but the political will to do anything about it has been lacking. Fresh water itself is a pollutant in brackish and saline ecosystems. Discharges from the lake weren't only fresh water, but fresh fertilizer-laden water. 

Lake Okechobee feeds the Caloosahatchee River on the west coast, and the St. Lucie river on Florida's east coast. Discharges to the west contributed to an existing red tide in the Gulf. "Our" red tide here on the southern Gulf coast is caused by a population explosion of a dinoflagellate called Karenia brevis. Karenia brevis can't survive in fresh water, but while the west coast was coping with beaches strewn with dead fish and marine mammals, and more, the east coast sustained equally disastrous consequences due to a nutrient-fed bloom of blue-green algae. Some places, like Sanibel Island, near the mouth of the Caloosahatchee,  got the worst of both worlds. Sanibel even had to deal with a 21-26 foot-long dead whale shark that washed up on one of its beaches. (Reports on the size differ). Florida lost numerous dolphins, sea turtles, and approximately 13% of the manatee population.

Florida lost numerous dolphins, sea turtles, and approximately 13% of the manatee population. 

The state sustained millions of dollars in lost tourist revenue as well as cleanup costs. Fisheries and related business such as marinas, fishing guides and boat rentals also suffered catastrophic losses. With no income tax, Florida depends heavily on tourism revenue and taxes, and the blow was bad enough finally to jolt some political actors awake. It's too bad that it takes a massive pocketbook issue like this to speed up significant corrective activity. One would think that degraded ecosystems and lowered quality of life would be enough.

Karenia brevis produces a neurotoxin that builds up in the food chain. Wind causes it to be aresolized, and many people living near the coast, including me, end up with real respiratory distress from red tides. Some people even need to be hospitalized. It's quite possible that it contributes to the deaths of marine mammals and sea turtles, which all breathe air. This January hundreds of dead fighting conchs washed up on one Marco Island Beach. If you think dead fish smell bad, wait until you get a whiff of rotting mollusks! Our canal turned a nasty reddish-brown color, and the fish, first catfish and mullet, started floating belly-up. 




Red Tide in Our Canal


After a few weeks' absence, red tide is back in the region, if not in our own backyard. The bloom gets blown or carried out by tides into the Gulf. When we get westerly winds it blows back in. This time around it is affecting fish-eating birds such as royal terns, cormorants and pelicans, along with fish, mollusks and sea turtles.

-----------------------------

The cooler weather this fall and winter has given us a bit of seasonal color. Some years the Virginia Creeper stays mostly green, but this year my neighbor's vine, creeping through the slats in our fence, sported lovely reds and violets. It's a pretty vine, even green, but it is too rapacious for most landscapes - especially small ones. Her yard crew pulled it out shortly after I made my sketch, but it will pop up again. 




Virginia Creeper - Parthenocissus quinquefolia


In the meantime, dune sunflower, other seasonal flowers, and visits by migratory birds keep the gloom and doom away. I even saw a leucistic grackle, something I'd never heard about before. The feathers on its head were startling white. I haven't seen it since.

Corkystem Passionvine


 Corkystem passionflower (Passiflora suberosa L.) is a mainstay of my butterfly garden. I just wish it would grow where I want it instead of collaborating with the birds to migrate to places where it is a pest. So far it has resisted my attempts to train it up a trellis or fence, yet it scrambles exuberantly in, around, through, and over shrubs and trees. If it has nowhere to climb, it spreads happily over the ground, especially where I have planted native heliotropium (Heliotropium polyphyllum). I could leave it as a ground cover, but since it is a vine, it presents a tripping hazard. I have a lot of digging out and potting up ahead, because I need to save at least some of the volunteers.

The genus Passiflora is the larval host for the zebra longwing, julia longwing, and much under-appreciated Gulf fritillary. The striking, orange Julias are uncommon in our garden. They tend to show up in a bunch and then disappear for years. We sometimes get zebra longwings, but they really prefer a shadier habitat than our yard offers. Zebra longwings roost in long chains at night, and the sight of such chains is absolutely breathtaking. The zebra longwing is Florida's state butterfly.





Gulf Fritillary Caterpillars on Passiflora suberosa

The beauty of a Gulf fritillary is hard to capture in paint or with my  very basic camera equipment. A newly-emerged adult gleams bright copper-orange, like the proberbial new penny. The undersides of the wings have a pattern of iridiscent silvery patches which reflect light spectacularly and brilliantly. 



The scanner cannot capture the silvery flash of the underwings.
These are dead individuals I have collected from the yard.


Passiflora suberosa is one of 7 species of passionflower native to Florida, but the purple passionflower, P. incarnata, is the only other one which occurs naturally in this area. Several exotic species, like the flamboyant scarlet passionflower ( P. coccinea) also flourish in the state. P. incarnata is a large vine, has a showy purple flower, and will get devoured by caterpillars. It dies back during our dry season.

"Maypop"  is another common name for P. incarnata. When I was a child we lived in South Carolina with my grandparents and unmarried aunt while my father served in the Korean War. I tagged along with my Aunt Iola, whom I called "Ant Ola." (I still pronounce "aunt" as "ant").

Even though I was afraid of the cows, who seemed awfully big, I liked accompanying my aunt when she took them out to pasture every morning. What I later realized was P. incarnata grew wildly in one spot. I asked her what they were, and she replied, "Maypops." When I asked her why, her answer was, "because they may pop and they may not." It is fascinating how certain little things can be preserved so vividly in our memories.

Corkystemmed passionflower is much more diminutive, and far less showy than its purple and red cousins. I agree with Rufino Osorio, who writes that while it first seems to have no obvious horticultural appeal, it's merits show themselves over time. The vine begins tender and green, and gradually adds ridges of corky material until it is enclosed completely.  Near the roots of an undisturbed vine the stem can reach a diameter of an inch or more, and certainly presents an interesting texture. 



Passiflora suberosa
Notice Corky Stem




The leaves have longish petioles and alternate around the stem. The surfaces are smooth, and the color varies from a yellowish green in bright sun to a more intense green in shade. The petioles have 2 raised "dots" opposite each other close to the base of the leaf. These are extrafloral nectaries. The plant  often displays "heterophylly," a fancy term for having leaves of different shapes. They can be simple and entire, or partially or deeply lobed. The presence of heterophylly in the plants in our yard varies, probably depending on what has been pollinated. Roger Hammer writes that lepidopterists surmise that the varying shape is a means to fool the butterflies so they don't lay as many eggs on the plant. The vine climbs and clings by tendrils emerging at the base of the leaves.


Heterophylly in Passiflora suberosa


The flower is small and delicate, about one-half to three-quarters inch in diameter. What look like petals, but really are sepals, are white or pale spring green. Pollinators of various sorts like them, because they produce a lot of berries throughout the year. The fruits start out green, turn blue, and then blue-black when ripe. Sometimes they have a chalky "bloom" like blueberries. They are roughly spherical and about a quarter-inch in diameter - about the size of a Spanish caper. They don't taste bad, but contain so many tiny seeds that they are mostly grit. Better leave them for the birds.



That brings us back to my struggle to keep the vine from eating the garden. The place it thrives most vigorously is all through and over a clump of bougainvilleas. The bougainvillea's vicious thorns and dense growth prevent me from getting at the passionvines' roots, and even if I did, the mockingbirds would reseed them promptly. They effectively cultivate the vine because they poop as they forage for the berries. The bougainvilleas aren't native, but they don't consume any resources beyond space and rainwater. The tiny white flowers nestled in the plant's hot-magenta-pink bracts attract a fair number of small pollinators, and the mess of bougainvillea branches and passiflora vines provides a prime nesting site for the mockingbirds. They have reared several successful broods there over the last few years. 

So it's a standoff. I can't beat it, so I settle for beating it back when it threatens, kudzu-like,  to suffocate the other plants. And I do like the butterflies.

Passiflora suberosa ranges from the Caribbean through Florida and the lower Rio Grande Valley, Mexico, and Central and South America. It has spread through much of the world, probably with the help of birds, and is considered an invasive exotic in serveral locales. It has a long history of use in folk medicine. It can withstand quite dry conditions if it has a little shade, but appreciates more water. It probably would not thrive in permanently soggy ground.

Fall Behind

 Looking out the dining-room window, my frequent perch, I see an abundance of color in the front yard. The bougainvillea has burst into another flush of bright magenta bracts, with their tiny, enclosed white flowers. Scarlet sage, Salvia coccinea, is blazing with impossibly red flowers. 

I tried to establish this plant unsuccessfully for years. A while back, though, one of my sisters gave me a pot of something else with a Salvia straggler, and it has spread itself throughout the back yard as well as in front. When it gets leggy and unsightly, which it does,  I either cut it back to the last green leaf, or just break off the now-brittle stems.



Scarlet Sage, Salvia coccinea



Blue-gray Eliott's love grass has peaked.Now it's drying, and its multiple seed-laden inflorescences are brittle enough to break off in the wind. They also like to work their way up your pant leg.  Pink muhly blooms later, and is also now past its prime. Its multitudinous inflorescences are somewhere between pink, purple and magenta. A clump of muhley grass by itself is a grand specimen, and it is really stunning in a mass planting, especially when there is just hint of breeze. Mounds of it billow and blow in a highway median a few miles away. 

Goldenrod, Solidago sp., has been blooming since June. Mine was a pass-along plant from a now-deceased friend in the local native plant society, who warned me, "once you have goldenrod, you'll always have goldenrod." Every time I root out another clump of suckers - goldenrod has expansionist tendencies - I remember Freda and her down-to-earth wit. Right now it is growing intermixed with a large, spreading mauve lantana, and the color combination works. I didn't plan it that way, but the goldenrod moved in on the lantana, and the 2 seem to coexist reasonably well, perhaps because the lantana stays low and the goldenrod reaches for the heights.

Florida has  19 species of goldenrod, and apart from the few that don't occur down here, I'll be damned if I can identify mine. I'm probably overthinking the process, but every time I think I am keying it out successfully I find a characteristic that nullifies it. Besides, I think they hybridize fairly promiscuously. 


"My" Goldenrod from Freda



Even though it blooms all summer here, goldenrod still seems to symbolize fall like pumpkins, asters, and fresh apples. Its numerous bright, saturated yellow-gold heads are intensely attractive to insects. Butterflies do use it in our yard, but they are far outnumbered by the wasps and bees that find it irresistible. 







In the photo above, a leaf cutter bee, Megachile sp., gathers pollen. The photo doesn't show it, but these medium-size bees collect pollen on their abdomen. I don't think the megachile in our yard is native, but I can't see that it does any harm. This species builds cylindrical egg champers in underground tunnels. It also will use holes for oarlocks and unused garden hoses. It cuts uniform oval shapes for the sides, and perfect circles to close off the egg chambers. Each compartment is about an inch long and a quarter-inch in diameter. The bee will make several chambers in each nest. It doesn't matter if the entry hole gets covered, either by shifting sand or waterborne debris. I extracted a cylinder once and kept it in a plastic dish at my workspace. All the cylinders produced an adult bee within minutes of one another. I liberated the bees after they hatched. 






Paper wasps, Polistes sp., also love the flowers. In my experience, most bees and wasps aren't particular aggressive when they are feeding. Once, though, a big bumblebee traveled from at least 6 feet away just to sting me, so I don't know what its problem was. This wasp is in no peril, but its perch reminds me of times I've had one foot on the dock and the other one on a boat that was inexorably moving away. (There is no end of entertainment watching boats come and go at a boat ramp or dock. As long as nothing tragic happens, you can laugh, but you have to remember that sooner or later it will be your turn to look stupid). 

Goldenrod flowers and leaves have been used medicinally for centuries. In fact, the genus name, Solidago, means something like "to heal or make whole." It also is a traditional dye plant. I can't speak for all species, but this one is extremely forgiving of sandy pseudo-soil and drought. Its tall spikes could be staked, but I sort of like to let it sprawl and flop. It gets beaten flat by a hard rain, but usually more or less recovers. 

Alas! All my wonderful color is in danger of being obscured by rampant weeds and overgrowth of natives I have allowed to self-sow. Now that the weather isn't quite as hot, I need to get busy  before Code Enforcement shows up. Cleaning up the yard will be a great antidote to stress from COVID and politics. The Presidential race seems decided, but the country remains as bitterly divided as ever. We all need to chill out a little and go plant something.




This post is woefully late. Sometimes life just happens. Eta scared us, but gave us a miss, though we had winds strong enough to flatten the goldenrod, coreopsis, and Elliott's asters. Most are now trying to straighten out, but I probably will have to cut the coreopsis back because its stems are so incredibly thin it's hard to imagine that they hold up a whole flower  head even in the best of circumstances.

I haven't figured out how to make links in the new Blogger format, but for more information you can refer to the posts listed below.

Simpson's Stopper

 Simpson's stopper, Myrcianthes fragrans, generally grows as a shrub or small tree up to 25 feet tall.  It is vary variable in form, and also can be pruned into any shape desired. It's formally pruned in many parking lot hedges, which is kind of too bad, since the constant whacking back vastly reduces flowering and fruiting. So even though many people in South Florida see it regularly, they don't notice it. On the other hand, the resulting dense growth produces a good nesting place for mockingbirds. 

 The Simpson's stopper in the front yard could be healthier, which is worrisome.  It's one of my very favorite plants, and it plays a vital ecological and esthetic role in our yard. Anchoring the front landscape design (such as it is), is not the least of its virtues. If it goes, it will leave a big hole. 




It started out as a multi-trunked containerized plant. I liked the outward spread of the trunks, so I left them. As it grew, I removed lower branches, partly because they were intruding on the path. The open, tiered canopy that developed is one of the plant's charms now. I just wish it were a bit fuller. "Limbing" it up also reveals the gorgeous bark, sometimes a perfectly smooth pale tan, as though it were sanded, and at other times turning reddish and peeling, a little like a crepe myrtle. The smooth bark phase is likely the source of one common name, "naked-wood."




Removing lower limbs also keeps the landscape more open and less-congested. It makes a nice screen between us and our neighbors to the left, but it isn't so dense that I can't see through it to their magnificent large Opuntias or the houses across the street.  No matter what your viewpoint is, you can see through and beyond the plant, so you are tempted to explore further. One of these days I am going to relocate one of my waterlilly pots so that birds can flit down for a drink or bath, and then retreat into the protective shade of the stopper.

The plant is evergreen, with opposite, mostly ovate leaves about 1 to 8 cm long,  and 1 to 4 cm wide. They are tough and leathery, with slightly underturned margins to reduce water loss. Depending on sun exposure, the leaves range from bright yellow-green to dark olive. The underside is a paler green. The leaves are covered with small glands, which appear as bumps on the upper side and as black or green dots on the underside.  I've never noticed any fragrance emanating from the leaves like it does from firs or spruces. Crushing the leaves, though, releases a fresh minty aroma something like eucalyptus oil. That's not surprising, since both are members of the Myrtle family, Myrtaceae.




In contrast with the leaves, the flowers really live up to their species epithet,  fragrans.  The plant blooms and fruits several times a year, depending on rainfall and temperature. When Simpson's stopper is in flower the air around it is filled with a spicy sweetness somewhere between the heavy, almost cloying odor of gardenias and the light, fleeting sweetness of citrus. When it is flowering I visit it several times a day, especially in late afternoon or early evening, just to breath deeply, as though I somehow could capture an olfactory  memory. Who needs mind-altering drugs when it is possible to wallow in pure sensation just by standing near a fragrant shrub and inhaling?




The all-white flowers grow in clusters on stalks that arise in the angle between leaf and stem. I think normally there are 5 tiny petals, though the one in my sketch above has 4. The numerous fine white stamens provide the main attraction, though. They practically obscure the petals, and a Simpson's stopper in full bloom looks like  the fairy godmother has waved her sparkle-trailing magic wand over it. The flowers are constantly humming with various pollinators, including beetles. Butterflies don't seem particularly fond of them, though. 




Flowers give way to rounded or somewhat pear-shaped fruits, often borne in pairs  - hence another common name, "twinberry stopper." They eventually reach a size somewhere between a blueberry and small olive, starting out green, then passing through yellow and orange stages before their final bright red. Mockingbirds gorge on the fruits, and if they happen to be frequenting the yard at the time, bluejays and cardinals also gobble the berries. The fruits are edible, somewhat sweet and not too dry, but for me leave an unpleasant bitter aftertaste. Volunteers pop up around the yard, evidence of the bird's activities. The plant also suckers, and probably could be propagated by severing them, too.

Apart from its other virtues, the Simpson's stopper functions as a kind of activity center in the yard. Even when they aren't feeding, birds like to perch on its branches. One July morning I made notes of what was going on around me while I sketched the fruits. I sat quietly enough that a mockingbird that had been flushed by my initial setup returned to the opposite side of the plant to continue eating. A shiny June beetle had its head stuck into a fruit, so intent on gorging that it let me manipulate foliage around it to make a photo. You can see a bit of my finger at the top of the photo.




Small bees and wasps buzzed amid the foliage and remaining flowers. Two other species of beetles were devouring fruits. Two strange insects that I couldn't ID were mating in the shrub's interior. A green darner dragonfly reconnoitered in search of prey or just patrolling its territory.  




I am wearing out the phrase, "superlative native plant," but that is because so many Florida native plants are, indeed, superlative. From its undemanding nature, repeated flowering and fruiting, glossy evergreen foliage, wildlife and landscaping value, Simpson's stopper certainly qualifies. It needs little water or fertilizer after it is established, and ours has survived major hurricanes Wilma and Irma with minimal damage. Though it gets pretty well defoliated by the salt-laden wind, it recovers quickly. 

It is named in honor of Charles Torrey Simpson (1846-1932), a noted South Florida plant explorer, snail expert, naturalist and nature writer. True stoppers are in the genus Eugenia, which also is in the Myrtle family. Simpson's stopper resembles them superficially, hence the most common common name.

August

This August has been something of a slog. And now we're already in the 3rd week of September! Medical procedures, mounds of paperwork, and heat indices into the 'teens have combined to keep me inside. Outside, things are occurring in the yard at a frantic pace. While spring ushers in a flurry of new growth in anticipation of rain, late summer shows a mad rush to grow and reproduce before the dry season begins.

There have been several waves of polydamas swallowtails after I blogged about them in July. In fact, a new adult was flying around last week. Predatory yellow jackets have been in evidence most, but not all, of the time. I don't know whether the butterflies hatched here or flew in from elsewhere. I've looked for chrysalids, but our badly overgrown yard offers a vast number of places to hide one. 

Our yard is home to many native plants. While they may struggle in their actual habitat, put them into a garden where they receive a modicum of care in somewhat amended soil, and they can run rampant. Mother Nature doesn't know a lot about sharing, and just about any plant that grows reasonably well here will try to take all the space. I try to scan all the bushels of vegetation I pull out or  prune back for evidence of caterpillars, cocoons or chrysalids, and baby tillandsias, but I'm sure I miss some.

 I  keep several water garden pots though I don't have any native waterlilies or lotus. The waterlilies bloom most of the time, which reminds me that I haven't even gotten around to fertilizing these heavy feeders yet. The lotus are mostly bloomed out by the end of July, and even beginning to go dormant by this time, but I had a few isolated late bloomers much to my delight.



                                                    Lotus, "Green Maiden"


Coral honeysuckle, Lonicera sempervirens, blooms most of the year here. It was in full flower in the middle of March. It may not make as impressive a show now, but the flowers haven't stopped. I couldn't get it established in Georgia, where it is native, but it flourishes here in sw Florida, which is south of its normal range.  It is a favorite of hummingbirds during their migrations to and from more southern climes, as well as many species of butterflies. Problem is, I've got it planted along a fence on the side of the house, so we miss most of what goes on with it. It is another proverbial "trouble-free" and "drought-tolerant" plant, and it also tolerates our flooding rains.


                                                Coral Honeysuckle

I finally got the bird pepper (Capsicum annuum, var. glabriusculum) that I bought way back in March  into a bigger pot. It was beginning to decline seriously before I did anything, but has responded beautifully to better circumstances. The birds weren't finding it where I put it, so I moved the pot to under a Simpson's Stopper (Myrcianthes fragrans), which is a favorite perching and foraging space for mockingbirds. Some of the fruits have disappeared, so something is eating them. 

This tiny pepper is a form of the ancestor of all our  peppers. It has a real bite, but the sting doesn't continue to linger and burn like many hot peppers. It's a great addition to all sorts of dishes, especially Tex-Mex and stir-fry. It's a  diminutive plant for starters, and its structure is so dense and compressed that it's hard for me to figure out just how things are arranged.




An invasion of Eurasian collared doves was an unwelcome event. Sadly, they discovered the Jamaica Caper, and literally shook the small tree with their clumsy weight as they stripped its fruits. The mockingbirds got some, but these aliens, imported years ago for hunting, probably got most. Our native mourning doves are delightful and coo melodically, but these boors have a call like "Raaaalf!" I always think of somebody barfing when the Eurasian collared doves are around.

The starry rosinweed (Silphium astericus) which I bought at the same time as the bird pepper, but planted right away, has outdone itself and already formed a second flowering clump. It has dark green, coarse leaves that can get 6 inches long or more, and the basal rosette is persistent. The erect, branched flowering stalks grow at least 18 inches tall. It has been blooming nonstop since late April/early May. I think I have the variety simpsonii, which occurs naturally along Florida's coastal plain, and is more tolerant of heat than some other forms. It will be interesting to see what it does once the rains stop. The butterflies and other pollinators were quick to discover it.  




                                        Starry Rosinweed

Elliott's aster (Aster elliotii) has produced its usual weedy-looking mass of skinny stems. I keep it because it is so stunning in full flower. Otherwise it is something of an eyesore, and since it spreads by rhizomes it will colonize any area that is even slightly moist. No illustration here - it is surprisingly difficult to draw or photograph a mess!

Last, but not least, one of my ponytail palms, Beaucarnia recurvata, bloomed. This one was a sort of gift from my late next door neighbor who didn't want it and suggested I take it. I have a problem letting things die ( one reason the yard is so overgrown - I don't pull out all the volunteers) so I took it. It was humming with honeybees and perhaps some other smaller pollinators.




This stem succulent has a very swollen base, and is not closely related to palms at all. It eventually will grow too large for this yard, but by then I will be long gone. Given the way old houses here are scraped away and replaced with narrow, 3-story mansionettes built all the way out to the setbacks, my tiny piece of semi-natural habitat will vanish too. It's a melancholy thought.
