Clinopodium georgianum is a low, aromatic shrublet of the mint family, grown for strongly scented foliage and clouds of soft pinkish-lavender flowers from late summer into fall, peaking around September when much of the garden is winding down. Where the scarlet calamint is a hummingbird firework, Georgia savory is the quiet one: smaller flowers, softer color, and a season that arrives when the bees have run short of options. Crushed, the leaves smell frankly minty, with a sweet edge that one nurseryman has compared to expensive peppermint candy.
Piloblephis rigida, wild or Florida pennyroyal, is a compact evergreen native mint from the sandy scrublands and pine flatwoods of Florida. The plant forms a low, tidy mound of fine, needle-like foliage that carries a clean, resinous, minty fragrance, released at a brush of the hand or on a warm afternoon in the sun.

Clinopodium coccineum is a small, aromatic, semi-evergreen subshrub of the mint family, native to the deep, well-drained sands of the southeastern coastal plain from Mississippi and Georgia down into Florida. The loose, open frame and small, spicy-scented leaves would earn a quiet place on their own, but the flowers are the event: scarlet tubes an inch or two long, held out like little trumpets. Bloom comes heaviest in spring and again in fall, with scattered flowers through the summer between, and in the mildest gardens of zones 8 and 9 the plant will open something in almost any month the weather stays soft.
A small shrub of the Cumberland Plateau, found only on the flood-scoured cobble and sand bars of three river systems in eastern Tennessee and a sliver of Kentucky: the Big South Fork of the Cumberland, the Caney Fork, and the Obed. The rest of the Conradina clan keeps to the sand scrub of Florida and the Gulf Coast of Alabama, sun-baked and semitropical. This species took a different path, north into the cooler uplands, and is the only member of the genus that never reached Florida at all. The cold-hardiness that came with the move is the gift to gardens farther north.
‘Amber Blush’ is a soft-toned selection of the native scarlet calamint, Clinopodium coccineum, an aromatic, semi-evergreen subshrub of the mint family from the deep sands of the southeastern coastal plain. Where the wild species flowers in hot scarlet, this clone brings a gentler and more complicated color to the same tough, hummingbird-visited plant: bright yellow washed with orange, deepening toward amber.
Pieris phillyreifolia, the climbing fetterbush, is one of the strangest and most wonderful of Southeastern natives, an evergreen member of the heath family with a habit unlike any other hardy shrub. In cultivation the plant grows as a neat, small evergreen shrub of two to three feet, clothed in narrow, leathery dark green leaves about an inch long.
Threadleaf bluestar is grown for two seasons at once: a haze of soft, powder-blue stars in late spring, and a billow of fine, needle-thin foliage that turns a blazing clear gold in fall. Native to the Ouachita Mountains of central Arkansas, Amsonia hubrichtii forms a large, dense, shrub-like clump of upright stems clothed in those threadlike leaves, and the autumn color alone earns a place in any sunny border.
A yellow-flowered butterfly bush, Buddleia x weyeriana 'Honeycomb' is a vigorous hybrid of Buddleia globosa and Buddleia davidii that the great Dr. Michael Dirr judged better than the older 'Sungold'. The plant came to Dirr from Crathes Castle Garden in Scotland, bought as the variety 'E.H. Wilson' but proving to be a very different and superior yellow butterfly bush, named 'Honeycomb' and a standout in Georgia trials, flowering as late as Thanksgiving.
Hypericum lissophloeus is the tree among the St. John's Worts, a graceful evergreen that climbs to ten feet or more on slender trunks dressed in smooth, copper-colored bark that peels in thin sheets. The leaves are needle-fine and deep green, so that from a distance the plant reads almost like a small conifer until summer, when small bright yellow flowers scatter along the stems and settle the question of family.
Agarista populifolia, still catalogued nearly everywhere as Leucothoe populifolia, is the giant of a group otherwise built low to the ground. Where most leucothoes hug the shade at knee height, this one rises, sending up tall, erect stems that arch at the tips into a fountain of glossy evergreen leaves, and given years and room the shrub can pass for a small multi-stemmed tree of twelve to fifteen feet.
A small, slow Japanese cedar that flushes the color of cold lemonade in spring, pale, almost translucent yellow, then settles into soft chartreuse through summer. The foliage stays juvenile throughout, fine and feathery rather than the awl-shaped scale of a mature Cryptomeria, which gives 'Lemonade' a softer presence than most gardeners expect of a conifer. This is texture you can run a hand through.
Myrica rubra, the Chinese bayberry or yangmei, is a fruiting evergreen tree from the misty mountains of East Asia, revered for centuries across China and Japan for tangy-sweet berries and an elegant, shapely form. Imagine cherries and cranberries with a botanical lovechild that had the moodiness of a plum and the antioxidant punch of a superfruit, and something close to yangmei would be the result. The plants we grow are female, tissue-cultured clones of a named selection.
Copper Canyon daisy is a big, aromatic, autumn-flowering marigold from the mountains of southern Arizona and adjacent northern Mexico, grown as much for the scent as the show. Brush against the finely divided, fern-like foliage and the plant releases a strong, distinctive fragrance, a mix of citrus, anise, and marigold that some find intoxicating and others frankly pungent. Tagetes lemmonii builds a soft, shrubby mound three to four feet high and wider still.
Schlechtendal and Chamisso published this oak in 1830 from material gathered around Jalapa, in Veracruz, and the epithet they settled on, germana, is the Latin word for genuine, true, of the same stock. Neither botanist left a note explaining the choice. The common names have been more generous since: royal oak, encino roble, and best of all avocado-leaf oak, for foliage so long, leathery, and lustrous that the leaves could pass for those of a Persea. In the cloud forests where both trees grow, the resemblance is more than a coincidence of shape; the two share the same wet, mild, dripping world.
The lesser-known of the two Hong Kong roses in the Woodlanders collection, Rhodoleia henryi is a handsome evergreen shrub or small tree from southern China and Taiwan, still little grown in the United States and, like much of the genus, occasionally muddled in the naming. Set beside the sister species Rhodoleia championii, this plant carries narrower, more pointed leaves, and the species is reckoned the more cold hardy of the two, a useful distinction for gardeners testing the edge of the range.
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.
Mapleleaf viburnum does what almost no other native shrub will do: thrive in dry shade. Most of the eastern American natives that gardeners reach for, serviceberry, red buckeye, sweetshrub, oakleaf hydrangea, want steady moisture and at least a few hours of sun. Viburnum acerifolium is the one that walks into the dry, root-tangled, low-light pocket beneath an established oak or beech and simply gets on with the job. The native range is genuinely vast, from New Brunswick south to Florida and west to Texas and the Upper Peninsula of Michigan, in upland forests, rocky slopes, and the edges of bluffs, making this one of the most widespread and most underused native shrubs of eastern North America.
Iris virginica takes the genus name that Linnaeus borrowed from Iris, the Greek goddess who carried messages along the rainbow, a fitting patron for a family that scatters every color through the flower. The species epithet virginica records where botanists first met the plant, in colonial Virginia, though Southern blue flag ranges far beyond, threading wet ground from the Chesapeake down through Florida and west to Texas, and north into the Midwest. In the wild the iris is an obligate wetland plant, at home in marshes, wet meadows, swamps, and the shallow margins of ponds where the roots can sit in standing water for weeks at a time.
Polygala x dalmaisiana, the sweet pea shrub, is a fast-growing evergreen hybrid of two South African species (P. oppositifolia and P. myrtifolia), grown for a nearly year-round show of orchid-like flowers on an open, informal frame.
For a week or two in late spring, the Chinese fringetree vanishes under what looks like a fresh fall of snow. Chionanthus retusus is a deciduous small tree of eastern Asia, native across China, Korea, Japan, and Taiwan, and the whole performance turns on the flowering: dense, lacy panicles of narrow, strap-shaped petals, pure white and softly fragrant, break over the entire canopy until the leaves all but disappear beneath the froth. The genus name records the effect exactly, from the Greek chion, snow, and anthos, flower.
