Calluna vulgaris 'Gold Haze' is a heather grown as much for foliage as for flower: tight, upright sprays of bright golden growth that hold their color through the year and warm to a deeper gold in winter cold. Set in drifts, the plants knit into a low, even evergreen carpet.
Federally listed as threatened since 1991, which means this plant cannot be sold across state lines. South Carolina and in-person purchase only.
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.
Every nursery keeps a few mysteries, and this trailing evergreen euonymus is one of ours: a plant still awaiting a firm name, possibly Euonymus aculeatus, collected by Frank Bell high on Mount Emei (Emeishan) in Sichuan, China. Low and spreading, the stems carry long-pointed, finely toothed leaves about two inches long, glossy and evergreen, on a habit that hugs the ground and wanders steadily outward.
Hypericum reductum is the ground-hugging member of the family, a low, heathery evergreen that mounds and mats rather than climbing, rarely rising much above the knee. The stems are crowded with fine, needle-like, deep green leaves that give an almost coniferous texture, and through late spring and summer the whole low sweep is dotted with small, bright yellow, star-shaped flowers full of stamens.
The genus is the one that turned the Lowcountry blue. Indigofera gave colonial South Carolina its great cash crop alongside rice, the dye that Eliza Lucas Pinckney coaxed into commercial cultivation around Charleston in the 1740s and that filled the colony's coffers for a generation, made with skill drawn largely from enslaved West Africans. That fortune rested on a tropical cousin, Indigofera tinctoria, but the family trait runs through the whole genus, and the leaves of this one will give up the same blue if you care to steep them. We grow the plant for the flowers instead.
No genus carries more Carolina history in its name than this one. Indigofera means indigo-bearing, and indigo was the blue that built the colonial Lowcountry: in the 1740s a young Eliza Lucas Pinckney coaxed a successful crop out of the land around Charleston, and for a generation the dye stood second only to rice among the colony's exports, made with skill drawn largely from enslaved West Africans, until the Revolution cut the British bounty and the fields went quiet. The plant that did that work was Indigofera tinctoria.
Thelypteris acuminata is a handsome evergreen fern from the woodlands of Japan and eastern Asia, grown for glossy green fronds that arch softly and hold their color through the year. Unlike the many deciduous ferns that vanish in winter, this species keeps a steady, structural presence in the shaded garden, one of the reasons the plant is prized where an evergreen fern is wanted.
The southern shield fern carries a longer pedigree than most ferns in cultivation. The type specimen was collected by Alexander von Humboldt and Aimé Bonpland near Cumanacoa, in the cloud-shrouded country around Caripe in northeastern Venezuela, during their five-year expedition through the equinoctial Americas. Decades later the German botanist Carl Sigismund Kunth, Humboldt's assistant in Paris and the man who would spend years describing the ten thousand and more specimens the explorers shipped home, became the namesake when Nicaise Auguste Desvaux formally described the species in 1827 as Nephrodium kunthii. C.V. Morton moved the fern into Thelypteris in 1967, and recent molecular work (Fawcett and Smith, 2021) has shifted the name again into Pelazoneuron, though the older binomial remains the one in common horticultural use.
This is a Trachelospermum, one of the star jasmines, offered here as an unnamed selection. Like others in the genus, the plant is a twining, self-clinging evergreen vine with glossy, leathery, dark-green leaves that clothe a fence, trellis, or arbor in dense green through the year and take readily to clipping into a clean, structured cover.
John Bartram collected Xanthorhiza simplicissima from the Carolina mountains sometime before 1776 and brought the plant back to his famous Philadelphia garden, which tells you two things: that yellowroot has been in cultivation for as long as this country has existed, and that people who know plants have always recognized something worth paying attention to here. The Cherokee had known the plant far longer, using the roots, sliced open to reveal a vivid, almost electric chrome yellow, as a dye, a bitter tonic, and a medicine for ailments from mouth sores to stomach complaints. The active compound is berberine, the same antimicrobial alkaloid found in goldenseal, and the roots produce berberine in striking quantity. Xanthorhiza is Greek for yellow root, and the name is no metaphor.
Low, shining, and quietly territorial, Ardisia japonica travels on slender underground stems and knits a dense evergreen carpet eight to twelve inches high across ground that most groundcovers refuse. The leaves are gathered in loose whorls near the tips of the stems, glossy and finely toothed, dark enough to read as almost black in deep shade. Small white to pale pink stars nod beneath the foliage in midsummer, easy to miss unless you kneel, and the berries that follow ripen coral red and hang on through winter, often still bright when the next year's flowers open.
Ardisia japonica 'Hakuokan' is a jewel of the Japanese shade garden, a low evergreen groundcover whose small, glossy, leathery leaves are edged in a clean band of creamy white. The green species, called yabukoji in Japan and marlberry in English, has grown wild in the woodland understory of Japan, Korea, China, and Taiwan for ages, spreading quietly by underground runners into knee-low colonies. 'Hakuokan', a name that reads roughly as white royal crown, is a variegated selection prized by collectors, slower and more compact than the plain species and all the more luminous for the pale margin that catches light in a dim corner.
Ardisia japonica 'Hinode' is a variegated form of the Japanese marlberry, each glossy, dark green leaf marked with a broad gold band down the center. Low and slowly spreading, this evergreen carpets shaded ground at eight to twelve inches, lit by the gold variegation and dotted in fall with bright red berries that hold into winter.
Cephalotaxus harringtonia 'Prostrata' is the spreading Japanese plum yew, a low, wide-growing evergreen prized for lush, dark green, needle-like foliage and an easy way with shade. Where the species and its columnar forms stand upright, 'Prostrata' lays out horizontally, three or four feet high and twice as wide, layering into a handsome evergreen groundcover or low border.
The conradinas are dense, aromatic, low shrubs of the mint family, dressed in small, usually needle-like green or gray leaves and hung with little pale purple flowers. Six or seven species grow wild in the southern United States, most of them in Florida on sand or very sandy soil, and the genus carries an unusual weight of rarity: four species are federally listed, C. brevifolia, C. etonia and C. glabra as endangered and C. verticillata as threatened, with two more carrying state protection in Florida. Conradina canescens is the exception and the common one, a somewhat variable plant of the Gulf Coast dunes of northwest Florida and adjacent Alabama and Mississippi.
Conradina canescens ‘Gray Mound’ is a silver-leaved selection of the false rosemary that grows wild on the deep, pine-fringed sands of the northern Gulf Coast, in Alabama, Mississippi, and the Florida panhandle, where the species holds the back of the primary dunes and runs inland into sand pine scrub. A member of the mint family, this aromatic shrub carries soft, needle-like foliage in a ghostly silver-gray, and from March into November, heaviest in spring, offers pale lavender to bluish two-lipped flowers spotted with dark purple on the lower lip, which native bees work steadily.
Some years ago we introduced two selections of Conradina collected on the Styx River in southern Alabama, called 'Low Gray' and 'Low Green', and we hope those clones survive in cultivation somewhere still. On a return visit to the Styx River site we gathered several more cuttings from distinctly low-growing plants. This conradina haunts a sandy woodland and cutover near the Styx River, and may well represent a new, as yet undescribed species; what appears to be the same plant turns up some miles east on Blackwater State Forest in northwest Florida. The Styx River plant differs clearly from the taller, more upright Conradina canescens of the open Gulf Coast.
Oblongleaf twinflower, Dyschoriste oblongifolia, is a low, spreading wildflower of the American Southeast, a member of the acanthus family that carpets the dry pine flatwoods, sandhills, and open savannas of Florida and neighboring states. The common name comes from the habit of carrying the small, funnel-shaped flowers in pairs, twinned in the leaf axils along low stems, while the botanical epithet oblongifolia simply describes the neat, oblong leaves. An older regional name is snakeherb, a tag shared across the genus Dyschoriste.
Heaths and heathers run to dozens of species and hundreds of named forms, and most of them sulk in the heat and humidity of the American South. Erica × darleyensis, a hybrid of two European mountain heaths, Erica erigena and Erica carnea, is one of the happy exceptions, tough and adaptable enough to give Southern gardeners a real chance at a plant most only admire in cooler climates. The renowned plantsman Michael Dirr, in his Manual of Woody Landscape Plants, allows that if one wants to grow a heath in the southeastern United States, this hybrid represents a credible starting point.
