Autumnal Observations
Posted by piedmontgardener in Native Wildlife, piedmont gardening on October 11, 2020
Autumn color of Katsura Tree.
Autumn is making itself undeniably known in my part of central North Carolina. Every day, I see more leaf color along with more discarded leaves on the ground, scattered among acorns, walnuts, and many other fruits. Humidity has dropped (barring occasional tropical storm remnants), skies are deep blue, and in my yard, the air is perfumed by the unmistakeable fragrance of golden leaves of a non-native tree I planted 25 years ago. The Katsura tree (Cercidiphyllum japonicum) became a must-have for me when I saw it in the display garden of a local plantsman. He waxed rhapsodically over the autumn leaf scent, comparing it to ripe strawberries in sunlight and cotton candy. He was not exaggerating. Wonder Spouse thinks the fragrance that wafts from the autumn leaves of this tree on north breezes resembles cotton candy. My nose finds the scent to be more fruity — a cross between strawberries and ripe apricots, perhaps with a hint of sweet apple. The golden orange leaves and their distinctive perfume have become our signal that autumn has arrived. But it is most certainly not the only sign.
Cornus kousa on the left and Cornus florida on the right, both heavy with autumn fruits.
Bird activity has picked up again. They were always around, of course, but now they are making more noise again. Red-bellied woodpeckers and blue jays make a constant ruckus as they gather characteristically small acorns of the massive southern red oak (Quercus falcata) that dominates the top of our hill. It appears to be a big year for acorn production; dropped acorns cover the ground beneath this giant.
Bright fruits of American beautyberry adorn its branches.
Fruit eaters from squirrels to Eastern bluebirds, mockingbirds, catbirds, and many other species are chowing down on dogwood and American beautyberry (Callicarpa americana) fruits. Our non-native Kousa dogwood (Cornus kousa) produced so much fruit this year that branches touched the ground until the fruits fell or were devoured.
Flocks of migrating robins clean off whole trees and bushes in a day or two. Migrating warblers are still passing through on their way to their winter hangouts, and finally this week, we’ve begun spotting rose-breasted grosbeaks at the feeders, refueling for their southward journeys.
The photo is blurry, but trust me, that’s a river otter peeking at me.
The plaintive calls of green-winged teals once again echo across the floodplain from the beaver-built pond where they spend their winters. Great blue herons are more visible as they stalk creek waters among browning vegetation. Besides the grosbeaks, the highlight of this week occurred this past Tuesday morning, when my garden helper, Beth, spotted two, perhaps three, river otters frolicking in the deeper part of the creek. She hollered for me to get my camera, but I only managed one blurry shot of one peeking at us from behind the safety of an ironwood (Carpinus caroliniana). Wonder Spouse has now aimed one of our wildlife cameras on that part of the creek in the hopes that it will photograph them more effectively than I could.
The green ash (Fraxinus pennsylvanica) forest that dominates our floodplain and which has become infested with deadly invasive non-native Emerald Ash Borers glows in the dim light of dawn and dusk as leaves turn a soft yellow before falling. Ash fruits still dangle in large clusters on the branches of female trees. Knock-on-wood — evidence of the imminent demise of these ashes is not yet apparent. I am praying that the one experimental release of predatory wasps by experts from my state was successful beyond our wildest expectations.
With the departure of summer’s heat and humidity, I find myself tackling the infinite garden chore list as often as my joints permit. I’m collecting some of the abundant seed produced by native plants growing on our five acres so that I can share it with a friend who is attempting to re-establish native plants on a public greenway beside a local creek. The fall vegetable garden needs regular tending. I am happy to report that the broccoli crop is coming along nicely, along with myriad greens we will enjoy in winter salads. With Wonder Spouse’s help, the front water feature is drained, and plants in pots that live there all growing season have been cleaned up and relocated to their winter quarters inside the greenhouse.
Much remains to be done; the cooler air that continues to be delivered by frequent cold fronts reminds me constantly that many of the tasks remaining are time-sensitive. Fortunately for me, cooler air and the perfume from the Katsura tree’s leaves invigorate me body and soul as I race to complete as many tasks as possible before winter grips the landscape.

Welcome, Autumn!

Summer left as sweetly as she arrived this year, bringing needed rain overnight. We woke to sunshine, deep blue, cloudless skies, and a steady breeze bringing in cool, dry, autumnal air. If only every summer could be as kind as this one was to us. Oh, she wasn’t perfect. Her excessive June rains put fungal diseases into overdrive. My tomatoes were blighted beyond redemption by late July.
But the peppers remain productive. My sweet Italian Bull’s Horn variety, Carmen, is overwhelming us with scarlet fruits.
Carmens remain productive.
And the one purple cayenne plant I added (free seed — who can resist?) is still producing zillions of fruits. They start out deep purple, then pale to lilac, then suddenly go deep, hot scarlet.
First, the cayennes are purple.
Then, they go hot!
The vegetable garden is mostly flowers now. The nasturtiums went bonkers, thanks to Summer’s rains. They now own two full rows where the beans and tomatoes once grew.
Never have the nasturtiums displayed such prolonged enthusiasm.
And they’ll be popping up everywhere next year without any help from me. Their fat, curly seed pods are verging on ubiquitous.
Clearly, the nasturtiums have plans for next year.
Reproductive efforts were evident everywhere in my yard today, as I took my Farewell-to-Summer stroll around the yard this morning. Some plants are just now showing off ripe fruits.
Cornus florida berries won’t last long; my pileated woodpeckers adore them.
Beautyberry always lives up to her name about now.
Viburnum nudum fruits go pink, then deep purple, but you don’t see many purples, thanks to hungry birds.
Hearts-a-burstin’ is exploding with strawberry-like fruits.
Some plants only produced a few fruits this year. I think the rains actually inhibited pollination in a few instances. Case in point: my native spicebushes (Lindera benzoin). They produced few berries, and as soon as those ripened, they were devoured. I found one lone exception today, hiding deep inside the center of a plant whose leaves are just beginning to turn their characteristic autumn gold.
One lonely spicebush berry hidden deep within the shrub.
Most of my holly species are heavy with unripe berries, but one is already showing off. A deciduous species, Ilex verticillata, is loaded with crimson fruits. In another month, its leaves will drop, but the berries will likely linger well into late fall, even January some years. The fruits are usually a meal-of-last-resort for the feathered inhabitants of my yard.
Ilex verticillata berries ornament a still-green shrub.
Fruits of my deciduous Asian dogwood (Cornus kousa) are just turning red, looking quite like Christmas ornaments.
Cornus kousa fruits.
The wet summer was a boon to the legions of lichens that adorn the trees in my yard. Lichens are not only beautiful and essential to the transformation of dead plant material into soil. I’m told they also signal good air quality; lichens won’t grow in smog-filled skies.

Even if my calendar didn’t tell me that today was the Autumnal Equinox, I would have known it was imminent. My Seven-Son Flower Tree never fails to signal Summer’s departure as it transforms its clusters of sweet, white flowers into clusters of purple-red sepals that consistently fool hummingbirds into thinking nectar hides within their embrace.
Purple-red sepals signal Autumn’s arrival, even as a few white flower clusters persist.
Rain-softened ground today made weed-pulling almost enjoyable; cool breezes prevented early autumn sunshine from overheating me as I tackled yet another area of my yard overwhelmed by the invaders that Summer’s rains invited willy nilly everywhere in my yard.
Other inhabitants were not entirely happy with my Autumn clean-up activities. A large earth-colored American toad hopped frantically between my legs when I removed its weedy camouflage. Numerous ant colonies bustled about carrying pearl-colored eggs to safety when I disturbed their weed-covered homes. And an Asian Praying Mantis female glowered at me with unblinking emerald eyes from her perch atop a pink-flowering abelia.
Her work is nearly done, though. I spotted freshly laid mantis egg masses firmly attached to the branches of a nearby shrub. Perhaps she was cranky from all that egg-laying; perhaps the cooling breeze told her that her time was nearly over.
Autumn’s arrival signals many endings, it’s true. But abundant fruits, well-hidden egg masses, slumbering salamanders, toads, anoles, skinks, and myriad snakes ensure that Spring’s beginnings are just a winter’s sleep away. Now is the time to tidy up our yards, tuck in a few new shrubs and trees, and settle indoors for some well-earned rest. Now is the time to dream of coming snows and next spring’s gardens.
Happy Autumn, everyone!
Transitions

Signs multiply daily. Reddening leaves:
Cornus florida
Virginia Creeper vine
Fruits swelling.
Bigleaf Magnolia cone
Carmen Bull’s Horn Italian Peppers and some yellow Italian heirlooms
Cornus kousa fruits will redden soon.
Halesia diptera fruits dangle from every branch.
I first heard about it from the flock of American Robins that blew in about three weeks ago. As they stripped purple Pokeweed berries from magenta stems and gobbled elderberries, branches bent from their weight, they muttered among themselves: “Autumn’s on its way.”
Pokeweed berries
Raucous cries of Pileated Woodpeckers echo through the forest as they argue with greedy robins and complain about magnolia cones ripening too slowly. A few mornings ago just after sunrise, three of these crow-sized woodpeckers called and flew in circles over my head for a minute or so. Two were chasing a third, making it clear that the interloper was not welcome.
Umbrella Magnolia cone
Southern Magnolia cone
Ashe Magnolia cone
And today, as Wonder Spouse and I walked beside the creek, we startled Wild Turkeys on the other side. They squawked once, then ran silently to the blackberry thicket, where they disappeared amid its prickly greenness.
We were down by the creek so that Wonder Spouse could photograph this beauty for me:
Franklinia alatamaha
Our wonderfully wet, mild summer made our two Franklin Trees very happy. Both grew several feet higher, and the mature specimen produced more flower buds than I have ever seen before. Spent snowy blossoms littered the ground beneath it, still faintly emitting their gentle rose-like scent. I held down the branch, so that Wonder Spouse could take the shot. You can see its close kinship to camellias by the form of its breath-taking bloom. The leaves of our smaller tree are already sporting garnet hues. But the flower-producing tree remains green-leaved.
Every time I think the record numbers of swallowtail butterflies are waning, another wave of fresh-winged beauties descends on every bloom in the yard. The Chinese Abelia still plays host to dozens, even though its sweet white flower clusters are beginning to diminish, but that’s OK, because the Seven-Son Flower Tree is in full, fragrant bloom, attracting every pollinator in the neighborhood, from butterflies to bumblebees, mason bees, and hawk moths. I cannot use my front walk without getting bumped into by a floating winged beauty.
An Eastern Tiger Swallowtail enjoys the Seven Sons Flower Tree.
The abundance of butterflies has been a bonanza for predators as well. Myriad dragonflies pick off the lazy flutterers in mid-air, scattering severed wings of gold and black along the walk.
And the most certain early sign of autumn abounds: spider webs. As fast as I knock one down walking anywhere in my yard, the industrious weavers rebuild. A particularly clever female Writing Spider has declared her domain over the water feature in our front garden. The abundant blooming spires of Cardinal Flowers are irresistible to butterflies, and this fattening weaver is taking full advantage of that fact, even bending the top of one spire to anchor her web.
The direction of the bend points to the fat weaver’s sticky trap.
Yesterday, I saw her trap and devour at least two large butterflies. Today, she seems to have doubled in size.
Female Writing Spider awaits her next victim.
Perhaps in response to her rapid growth, today a male Writing Spider has built a modest web adjacent to this queen, even using a corner of her web as an anchor. Much smaller than the female he lusts for, he will wait for just the right moment to woo her. It won’t be long, I predict. Usually the females deposit their egg sacs in thick, winter-proof webs well before the leaves begin to fall in earnest.

Cricket songs now rule nights and mornings, replacing the steady thrum of summer cicadas. Occasional cold fronts rush in behind lines of thunderstorms, freshening our air for a day or two before summer reasserts itself, cloaked in humidity.
Autumn will dominate soon enough, that we know for sure. For now, we can revel in the transitions, as plants and animals shift from growth to fruit to sleep.
It’s a transitional time of year for many people too. Schools start, and birthdays occur in bunches, as those born under the sign of Virgo celebrate another dance around the sun. I send best birthday wishes to all my Virgo kin and friends, and most especially to my favorite nephew, AJR, who celebrates what many consider a milestone moment tomorrow. Happy Birthday, sir. May your journey lead you everywhere you want to go.
Happy Birthday, Virgos!
Autumn’s Fruits and Nuts
Posted by piedmontgardener in Favorite Plants, Native Wildlife, piedmont gardening on October 7, 2012
Autumn is only a few weeks along, but the occupants of my yard and gardens are progressing toward readying themselves for winter. For example, the lovely mushrooms in the above photo are sprouting up beside my driveway in growing numbers. As they grow from button stage (far left) to middle age (far right) and full ripeness (center), zillions of mushroom spores are readying themselves for release from the gills under the caps. Many colors and shapes of fungi are currently taking advantage of the cooler, damp weather here.
The Black Walnut had a very productive year. Hard hats to defend against falling nuts are no longer required when walking beneath it, but now one must watch every step to avoid slipping on the yellow-green orbs hiding in the grass.
The squirrels wait for the outer green husks to soften before they start working on these nuts.
The Red Buckeye had another bumper crop year. These nuts are poisonous, but the squirrels can’t resist carrying them all over the yard and burying them.
The outer husks crack open and drop the buckeyes to the ground. Some folks think these fruits are good luck.
The Beautyberry shrub and the big Hearts-a-burstin’ flourishing on the upper floodplain both had very productive years.
Even in deep shade, these colorful berries glow like Christmas ornaments.
Breaking hearts abound.
The Asian kousa dogwoods were also very fruitful. The evergreen one tended to produce fewer, fatter red globes like this:
The deciduous kousa dogwood must have been very thoroughly pollinated this year — yet another autumn beauty that seems to be vying for Christmas tree status.
This Cornus kousa dwells beside our back deck. Its leaves are just beginning to turn lovely shades of orange.
This recent visitor below was neither a fruit nor a nut, but it was so gorgeous that Wonder Spouse felt obliged to take its picture, and I’m glad he did. This was a new insect for us, a showy member of the dung beetle clan. Truly, if someone made a jeweled pin based on this creature, I would proudly wear it.
Meet a male Rainbow Scarab. The “horn” denotes its gender.
And here’s more of a side view:
Note the bit of spider web tangled in its horn.
This fellow was walking around our back deck. We suspect it stunned itself on one of our windows, staggering about just long enough for Wonder Spouse to document his visit. He flew off ten minutes later.
I’ll close today with a few more nuts — the animal kind. We seem to have a bumper crop of Green Anoles this year, perhaps the result of behavior like what I documented here. The front of our house faces west. Warmth from late afternoon sun combined with a flourishing front garden seem to have produced ideal anole habitat. One afternoon last week, I caught four basking on various parts of the front of my house — some large, some quite small.
The first one I saw was a large brown lizard that had trapped itself between my front door and the outer storm door. When I opened the inner door to go out, it frantically beat itself against the storm door until I could get it open. Here it is glowering at me as it recovers from its self-inflicted trauma.
Undamaged, but unhappy.
After taking that one’s picture, I noticed a small one basking on the front wall.
It was about six inches long, but quite skinny.
Then I spotted this green one hanging out around my bedroom window. It actually climbed the glass and seemed to be trying to peer inside.
I tried to persuade it that it will be far happier outdoors.
Finally that day, I spotted another green one below the bedroom window on the wall behind an overgrown rosemary shrub. It was more shy than the other three.
This rosemary started blooming last winter and only stopped during the July heat wave.
These anoles were all out on a very warm day. We had a string of 80+-degree days ahead of a cold front. I think perhaps they were all trying to soak up as much heat as they could before retiring to their winter slumber spots. I’m wondering if perhaps their abundance is making it difficult for them to all find cozy winter quarters, because of what I observed yesterday.
Yesterday was the last warm day before the arrival of a cold front that has dropped our temperatures about thirty degrees. And it was yesterday that Wonder Spouse noticed that a brown anole was actually on the inside of the window beside our front door. It must have slipped inside when one of us opened the door. It may well have been the same one that I caught between the two doors the day before.
Fortunately, it was quite cooperative about its relocation to the outdoors. We used a butterfly net, intending to scoop it up gently. But it chose to perch quietly on the rim long enough for us to escort it back outside to the garden, none the worse for its adventure.
Late yesterday as the sun was setting, one of the anoles did something even more unexpected — nuttier, if you will. I always leave my hummingbird feeder filled until the second week of October, or until I don’t see any hummers for a week or so. Yesterday when I checked the feeder before going inside, I saw this:
Yes, that’s an anole head peeking out from the middle. It’s curled up in the center cup where one can put water to deter ants.
I imagine the surrounding sugar water was quite warm from the late afternoon sun, and this little one thought it had found an ideal hangout. Of course, the water doesn’t stay warm at night, and any hummers trying to drop by wouldn’t know what to think, so we gently lifted down the feeder and encouraged the anole to return to the garden.
It really didn’t want to leave its cozy spot, but I think it was probably for the best.
I checked the front wall today without expecting to see any anoles. One brown one stuck its head out from behind a gutter for just a moment, then disappeared. Given our drizzly, chilly day, I was surprised to see an anole at all. I hope they are all settling down for a long winter’s sleep, along with all the other plants and animals that share our five acres of North Carolina Piedmont.
Early Summer Brings Chinese Dogwood Blooms
Posted by piedmontgardener in Uncategorized on June 2, 2011
Chinese dogwoods (Cornus kousa) are very lovely trees. Like our native dogwoods, the showy parts of the flower are actually four white bracts; the actual flower is the unimpressive-looking middle. Chinese dogwoods in my yard seem to be maturing to about the same height as my native dogwoods — maybe a tad shorter. They share the same lateral branching pattern that makes a blooming dogwood appear to float beneath the taller canopy trees.
Unlike our native dogwoods, which finished blooming in my yard back in April, the Chinese dogwoods begin blooming for me in mid-May. And one special variety I grow — Cornus kousa var. angustata — is just now reaching peak bloom. Here’s a close-up of one blooming branch to give you a sense of the spectacular flower-power of this tree:
Cornus kousa var. angustata
You can see that the flowers differ subtly from those of our native dogwood. I think of them as pointier. Here’s a close-up of the flowers:
Cornus kousa var. angustata flower close-up
See the roundish bump in the middle? That’s the early stage of one of the fruits forming. Chinese dogwoods don’t produce the berry-like drupes that our native dogwoods produce. Instead, the fruits are pinkish-red and look a bit like raspberries. It always amazes me how completely different the fruits of these two species are, because they look so much alike in other ways. Birds don’t seem to like these fruits as much as they do those of our native dogwoods, but the squirrels delight in them every early fall when the tree becomes loaded with these reddish globes.
One more astonishing thing about this particular variety — it’s evergreen. In Zone 7 and above, the tree remains reliably evergreen all winter long. That’s not to say it remains pristinely perfect. A deep cold snap or an ice storm will leave my tree looking ragged around the edges until the new growth of spring. But many winters, it’s quite eye-catching as it sits near my front door in January — clearly a dogwood — but with green leaves!
Actually, the leaves in winter become tinged with a deep maroon, which gives the tree a richness it lacks in summer. Now imagine this evergreen dogwood loaded down with raspberry-like fruits in early fall. Talk about four-season interest! Chinese dogwoods have one more asset — they are resistant to most of the diseases that plague our native dogwoods.
I will never forsake our glorious native dogwoods. I’ve already described how much I love them here. But Chinese dogwoods in my landscape extend the blooming period of this genus well into early summer, and the novelty of my evergreen dogwood — which is now after 18 years about 18 feet tall and 15 feet wide — is something I don’t ever think I’ll grow tired of enjoying. Here’s a parting shot of most of the tree, which graces one edge of our front deck:
