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.
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 once mingled with sea oats and longleaf pine. A member of the mint family, this aromatic shrub carries soft, needle-like foliage in a ghostly silver-gray, and from spring into early summer, sometimes again in the cool of fall, offers a flush of pale lavender to bluish, two-lipped flowers that native bees and butterflies work eagerly.
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.
The Latin gives away the joke before you have even seen the plant. Ficus vaccinioides, the Formosan creeping fig, is a fig that has decided to impersonate a blueberry: vaccinioides means resembling Vaccinium, and the small, glossy, obovate leaves running close along reddish stems really could pass for an evergreen huckleberry. They are no relation at all. They are a true fig, latex and all, just one that has shrunk to a few inches tall and given up any ambition of climbing.
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.
This plant is a botanical time machine. Sarcandra glabra belongs to the Chloranthaceae, a flowering-plant family with only four surviving genera worldwide and a fossil record reaching back into the Early Cretaceous, more than a hundred million years ago. Pollen and floral fossils of the Chloranthaceae are among the earliest evidence of flowering plants anywhere on Earth, and the family was already abundant when the dinosaurs were only in their middle age. Today Sarcandra is one of just four genera left from a lineage that once spread across what is now Portugal, Spain, and eastern North America, and most of that Cretaceous diversity is gone. The little plant in the garden is a quiet survivor of a family that mostly did not make it.
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.
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 variegated form of Confederate jasmine, or star jasmine, is grown as much for the foliage as the flowers. Each leathery, evergreen leaf is bordered and splashed with creamy white, often flushed pink in cool weather, and the leaves run larger than on most forms of Trachelospermum jasminoides, so the vine reads as a soft, marbled cloud of green and cream on a fence or trellis even out of bloom.
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.
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 all but this one (and one possibly new species) are federally listed as threatened or endangered. Conradina canescens is the common, widespread member of the clan, a somewhat variable plant of the Gulf Coast dunes of northwest Florida and adjacent Alabama.
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.
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 the cold-hardiness that came with the move is the gift to gardens farther north.
