Summersweet has long been a shrub gardeners plant by the nose. Native to the moist woods and pond margins of the eastern United States, Clethra alnifolia earned the old country names Sweet Pepperbush and Summersweet for the honey-and-clove perfume that pours off the white summer spikes, a scent that carries clear across a garden on a warm afternoon. Colonists found a further use for the plant: the flowers, crushed in water, raise a soft lather, and were once pressed into service as a field soap.
Clethra alnifolia, the summersweet or sweet pepperbush, is a deciduous native of the eastern United States, at home along pond edges, in damp woods, and at the margins of coastal swamps from Maine to Florida. The species spreads gently by suckers into colonies of upright stems, and earns the name sweet pepperbush from the small, peppercorn-like seed capsules that follow the flowers and hang on through winter. For all that, the summer flowers are the reason to grow them: erect bottlebrush spikes, intensely honey-scented, that open over many weeks in the heat of July and August when little else in the shrub border is in bloom.
The summersweets are among the most fragrant of American shrubs, native to the moist woods, swamp edges, and pond margins of the eastern United States, where the white summer spikes scent whole acres of low ground. Country people knew the plant as Sweet Pepperbush, for the peppercorn-like seed heads, and as Summersweet, for the honey-and-clove perfume; the crushed flowers even raise a soft lather in water and once served as a woodland soap.
Summersweet, Clethra alnifolia, is one of the great fragrant natives of the eastern United States, a shrub of moist woods and pond edges whose white summer spikes carry a honey-and-clove perfume across the whole garden. Colonists called the plant Sweet Pepperbush, for the peppercorn-like seed heads that follow, and Summersweet, for the scent; the flowers even lather softly in water and once served as a field soap.
Summersweet, or sweet pepperbush, is one of the most useful of the native shrubs for moist, shaded ground, and 'Hummingbird' is the compact, free-flowering selection that made the species a garden staple. Like the straight Clethra alnifolia, this is a stoloniferous deciduous shrub that forms colonies in moist, acid soil, valued above all for the upright spikes of intensely fragrant white flowers that perfume the whole garden in the heat of summer, when little else is blooming.
The Japanese clethra is grown for bark as much as bloom. Clethra barbinervis is a tall, tree-like deciduous shrub or small tree from the mountains of Japan and Korea, carrying somewhat fragrant terminal racemes of white flowers in summer, in the same sweet-scented family as the native summersweets. But the real distinction is the bark: smooth and polished, gray to warm brown, and exfoliating in age to a handsome patchwork that makes this one of the finest small trees for the winter garden.
Clethra fargesii is the Chinese cousin of our native summersweets, a graceful deciduous shrub from the mountain woodlands of central and western China, gathered and named for the French missionary-botanist Paul Farges. Kin to the better-known Clethra barbinervis, the Chinese clethra stays a little shorter and carries dark, glossy green leaves, broadest through the middle and sharply toothed, that color bronze-red to maroon before they fall.
Most of the summersweets drop their leaves and sleep through winter; Clethra pringlei keeps them. This Mexican member of the clan is a broad-leaved evergreen, a large, slow-growing shrub or small tree from the mountain woodlands of northeastern Mexico, and one of the more surprising plants in the genus for a gardener who knows only the deciduous American kinds.
Clethra alnifolia and the southern Clethra tomentosa are stoloniferous deciduous shrubs commonly called Summersweet or Sweet Pepperbush. They form colonies in moist acid soil and make good garden subjects. They are valued for their terminal spikes of fragrant white flowers in summer. Plant in sun or semi-shade and provide adequate moisture. This clone of the southern species has light colored backs of leaves and amazing flower racemes up to 16 inches long! This Woodlanders introduction is a plant we selected from the wild in the Florida Panhandle. It was the highest rated Clethra clone tested in trials at Longwood Gardens. Clethra tomentosa is native to the southern U.S.
Clethra alnifolia and the southern Clethra tomentosa are stoloniferous deciduous shrubs commonly called Summersweet or Sweet Pepperbush. They form colonies in moist acid soil and make good garden subjects. They are valued for their terminal spikes of fragrant white flowers in summer. Plant in sun or semi-shade and provide adequate moisture. This selection has leaves that are speckled and banded with cream to white variegation. Found by Mike Creel in Lexington County, SC. Plant best in semi-shade.
The summersweets are among the most fragrant of American shrubs, and the southern woolly summersweet, Clethra tomentosa, carries the whole tribe's gifts: colonies of upright stems in moist, acid ground, and terminal spikes of white flowers that pour a honey-and-clove perfume across the July garden. Country people knew the plant as Sweet Pepperbush, for the peppercorn seed heads, and the crushed flowers even raise a soft lather once used as a woodland soap.
Cleyera japonica belongs to the tea family, the Theaceae, alongside camellia and tea themselves, and shares the family's glossy, leathery, deep green leaves. In the plant's native Japan the species carries a sacred weight few garden shrubs can claim: this is the sakaki, written with a character that fuses the signs for tree and for god, and the branches are cut for tamagushi, the leafy wands offered at Shinto shrines for blessing and purification. Small, sweetly scented cream flowers open in early summer, followed by berries that ripen from red to black.
Cliftonia monophylla 'Berry Pink' is a rare, pink-flowered selection of the Black Titi, a native evergreen shrub or small tree of the southeastern coastal plain that normally blooms in white. The species haunts the acid bogs, pond margins, and titi swamps from the Carolinas to the Gulf, where the early flowers make the buckwheat tree one of the first and most important nectar sources of the southern year, the source of the prized titi honey.
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: showy scarlet tubes carried over a long summer season, held out like little trumpets that hummingbirds cannot resist.
'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 apricot clone brings a gentler, more complicated color to the same tough, hummingbird-loved plant.
Clinopodium coccineum 'Ohoopee Yellow' wears a contradictory name, since this is a clear, bright yellow-flowered form of a mint shrub that usually blooms in scarlet. The yellow form was originally shared with us by Ken Wurdak, who found the plant in Tattnall County, Georgia. We later lost our stock and got the clone back from Mike Creel, who had received starts from us years before. Such are plant sagas.
Clinopodium georgianum is a low, aromatic shrublet of the mint family, prized for highly scented foliage and clouds of pinkish-lavender flowers in late summer and fall, when much of the garden is winding down. Georgia savory makes a fine edging or front-of-border plant for sunny or lightly shaded spots with good drainage, and unlike most of the tribe, this southern native will grow in heavier soils as well as sand.
'Desi Arnez' (Clinopodium georgianum hybrid) turned up as a chance seedling in the garden of Robert Mackintosh, a cross of uncertain parentage that Woodlanders judged worth keeping and worth introducing. The likeliest account is a quiet romance between Georgia savory (Clinopodium georgianum) and a neighboring false rosemary (Conradina), two southeastern natives that seldom bother to cross the line between their genera. Botanists who keep their Latin tidy now file the result under the bigeneric name ×Clinadina, which is roughly how the field admits it never saw the match coming.
Clytostoma callistegioides is one of those vines that feels as though the plant wandered out of an old botanical expedition: vigorous, evergreen, and brimming with the sort of charm collectors once crossed oceans to find. A close relative of our native crossvine (Bignonia capreolata), this South American cousin shares the same athletic climbing spirit but dresses in glossier, more refined foliage and carries larger flowers.
Among the most bewitching sights in the summer garden, Colocasia esculenta 'Black Magic' rises like a gothic dream from the soil, the velvety, purple-black leaves casting deep shade and deeper admiration. Sometimes called the Jet Black Wonder, this dramatic taro cultivar has become a garden sensation across the South, beloved for bold color and architectural form.
