In July, when most of the shade garden has settled into a holding pattern of foliage and waiting, Aesculus parviflora opens for business. The timing is the first surprise. The flowers are the second. Each panicle is a foot or more of tightly packed white tubular blooms with conspicuous pink-red anthers projecting beyond the petals, the whole spike held upright above the foliage like something assembled by a botanical committee that could not decide between elegant and extravagant and chose both. A mature colony in full bloom in midsummer is among the more spectacular events available to the shade gardener, and the hummingbirds and swallowtails arrive reliably.
A small, bright green agave with a clean white stripe down the center of each short, broad, toothed leaf, Agave lophantha 'Splendida' is a compact, clumping selection of a species native to South Texas and Mexico. The variegated rosettes stay neat and low, a jewel-box agave for a trough, a container, or the front of a hot, sunny bed.
The genus name says it: Callicarpa, from the Greek kallos, beauty, and karpos, fruit, beautiful fruit, a genus named for exactly what it does. Callicarpa americana, the American beautyberry, is the southeastern native that gives the genus a calling card. From late August into November, the plant sets dense clusters of small drupes in a luminous magenta-purple, a color that registers as almost unreal in the late-summer landscape, somewhere between fuchsia and amethyst, with no real precedent among native fruits. The berries gather in tight whorls around the stem at every leaf node, all the way down the arching branches, so that a mature shrub in October looks less like a shrub bearing fruit than a ribbon of purple glass beads strung along the branches.

Everyone who grows the native beautyberry knows the plant by the autumn display: those improbable whorls of magenta-purple fruit circling every stem like something a florist arranged and forgot to bill for. 'Welch's Pink' is that plant, in a color the species was not supposed to have.
The white-fruited form of the Asian beautyberry, Callicarpa dichotoma 'Albifructus' is a quiet pleasure of the late-summer border: instead of the usual magenta, the arching stems hang with luminous, ivory-white berries in elegant clusters, cool and refined where the purple kinds are bold. Native to eastern Asia, in Korea, China, and Japan, the white beautyberry is smaller and more graceful than the American species, and all the more striking for the restraint.
Carex flaccosperma, the blue wood sedge, is a clump-forming native of the Southeastern woodlands grown for cool, glaucous, blue to blue-green foliage. The blades are wide for a sedge, to half an inch, faintly quilted along the veins, and they catch the light with a soft powdery sheen that lifts a shaded planting where most greens recede.
Distylium myricoides belongs to the witch-hazel family, Hamamelidaceae, an evergreen cousin of the fragrant winter witch-hazels, though the kinship shows in the flowers rather than the leaves. The Piroche form is a distinct, low-slung selection of the species, chosen for a broad, spreading habit and strong horizontal branching that make the plant read more as living groundwork than as an upright shrub.
Dryopteris ×australis is a fern that cannot, strictly speaking, reproduce, and is all the more vigorous for the lack. This is a natural hybrid, thrown wherever two Southern wood ferns grow within a spore’s reach of one another: the log fern, Dryopteris celsa, and the southern wood fern, Dryopteris ludoviciana. The cross comes out sterile, setting spores that never amount to anything, so the fern cannot seed itself across a bed the way a large fern usually will. Every plant in cultivation traces back by division to a wild clump found somewhere between Virginia and Louisiana, the greatest number of them in Alabama.
Morella pumila is the dwarf waxmyrtle, a low, native evergreen that keeps everything gardeners love about the common wax myrtle, aromatic foliage, waxy berries, and a tough constitution, and shrinks it all to knee height. Native to the frequently burned pinelands of the southern United States, the plant is an adaptation to that fiery world, staying small and spreading slowly into dense patches and colonies by underground runners.
Muhlenbergia dumosa, bamboo muhly, is a desert-born grass with the grace of bamboo, drifting like cloud shadow across the canyon floor. From the arid uplands and rocky washes of northern Mexico and southern Arizona, where sun-scorched cliffs and canyon walls shaped the character of the species, bamboo muhly evolved to thrive on dry air and lean soils, and yet carries the fluid elegance of true bamboo, swaying at the faintest breeze.
'Variegatus' brings light to the false holly. The spiny, holly-like evergreen leaves are edged in clean creamy white against a dark green center, so the whole shrub reads as a soft glow at a distance and a crisp, formal pattern up close. The variegation lifts a shaded corner the year round, a quiet luminance that the plain green species cannot offer.
Pistacia chinensis, the Chinese pistache, is a medium-sized deciduous tree and a close relative of the pistachio nut, though this species carries no crop for the table. What the tree offers instead is one of the finest autumn shows in the warm South: lustrous, dark green compound leaves that ignite, nearly all at once, into a fire of scarlet, orange, and red before they fall.
In Japan they call the shrub tobira, short for tobira no ki, the door tree, because the cut branches were hung in the doorway at Setsubun to turn back demons at the threshold of spring. The broken wood smells rank, which was rather the point: bad spirits, like most of us, would rather not walk through a bad smell. The genus name is kinder and more exact, pitta and sporos, pitch and seed, for the resin that coats the black seeds and glues them to whatever bird carries them off.
The English laurel is a large broadleaf evergreen shrub grown for bold, glossy foliage, spires of small white flowers, and, at times, small cherry-like red-to-black fruits. The species is variable, with a number of cultivated forms, and the plant is native to eastern Europe and Asia Minor.
If any native perennial could be said to hum, the honor would go to Pycnanthemum muticum. From mid to late summer the blunt mountain mint gathers a shimmer of broad, silver-frosted bracts at the top of every stem, and within them open dense heads of tiny pink-to-white flowers that draw an almost comic density of life: bees of every kind, wasps, butterflies, skippers, moths, and flies working the nectar from dawn to dusk. In a three-year Penn State study that monitored eighty-six species, no plant drew a greater number and diversity of pollinators.
Selaginella braunii, known in older texts as Selaginella involvens and in gardens as Braun's spikemoss or the arborvitae fern, belongs to one of the oldest surviving lineages of plants on Earth. The Selaginellas are not true ferns but spikemosses, an ancient group whose ancestry runs back more than three hundred million years, long before flowering plants reshaped the world. In the shaded understory of primeval forests these plants held their ground, and Braun's spikemoss carries that inheritance forward with quiet dignity.
A dwarf form of one of Japan's legendary Five Sacred Trees of Kiso, the goboku no kinbatsu, a select group of conifers protected by feudal law for centuries, reserved for imperial residences and temple construction, where commoners caught poaching the wood faced execution. The species, Thujopsis dolabrata, is endemic to Japan and known there as asunaro, a name that translates beautifully and a little wistfully as tomorrow it will become hinoki, a nod to the tree's resemblance to the more revered hinoki cypress, forever almost but not quite the more famous tree. Thujopsis is the sole species in the entire genus.
A native tree that bites back, and can numb a toothache. Zanthoxylum clava-herculis, the toothache tree or Hercules' club, is a small to medium deciduous tree of the citrus family, native along the coastal Southeast from Virginia to Florida and Texas. The genus name Zanthoxylum means yellow wood, and the species clava-herculis, the club of Hercules, names the stout, spiny, club-shaped trunk that is the tree's signature.
In the cool hush of shaded woods, Adiantum pedatum rises on slender, glossy black stems that hold the lacy green fronds in flattened semicircles, each a hand-turned fan or horseshoe of finely cut segments. Standing twelve to thirty inches tall, the northern maidenhair forms serene clumps that spread slowly on creeping rhizomes, never in a hurry. In early spring the fiddleheads emerge a rosy to burgundy hue and uncurl into the distinctive bird's-foot, palmately branched leaves that give the fern such grace.
A wide-spreading, suckering, multi-stemmed deciduous shrub of slow, deliberate growth, Aesculus parviflora var. serotina carries the same upright white bottlebrush flowers as the bottlebrush buckeye, but opens them two to three weeks later, well into the heat of summer. The overall shape is irregular and almost stratified, the branches layering horizontally, and the medium to dark green leaves turn a clear yellow in fall.
