Plants that turn their faces to the light. This is the roll call for the open, sun-struck parts of the garden, the borders and banks that bake from morning to evening, where the toughest, brightest, most floriferous plants do their best work.
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.
This is a tree you harvest from a boat. Crataegus opaca, the western mayhaw, grows wild in the flooded bottoms of the Gulf Coastal Plain, the cypress sloughs and pond margins of east Texas, Louisiana, and the Deep South, and when their fruit ripens in late spring it drops straight into the water and floats. For generations Southern families went out in May with boats, nets, and scoops to gather the bobbing red haws off the surface, a fast three weeks of work that turned into a year's worth of jelly. The name says as much: mayhaw, for the month, and haw, the old word for hawthorn.
The genus name comes from the Greek dichroos, meaning "two-colored," and Dichroa versicolor presses the idea further: bloom color shifts with soil chemistry much the way a hydrangea does, swinging from deep cobalt to soft mauve depending on how much aluminum a plant can draw up. The species epithet versicolor only doubles down on the point, promising a shrub that refuses to settle on a single shade.
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.
Golden dewdrop, Duranta erecta, is a member of the verbena family grown across the warm world for two ornaments the shrub carries at once: loose, drooping sprays of soft lilac-blue flowers, each with a darker eye, and long chains of round, glossy amber berries that hang like strings of wet gold. The common name catches that second gift exactly, while older names, pigeon berry and skyflower, catch the first. Native from Mexico and the Caribbean through much of tropical South America, the shrub has been carried into gardens throughout the subtropics, where the plant flowers and fruits nearly year round.
Duranta serratifolia, the tala blanco of northern Argentina, is a South American cousin of the familiar golden dewdrop and belongs, like all Duranta, to the verbena family. The species epithet serratifolia means saw-toothed leaf, for the finely serrated margins that separate this plant from the smoother-leaved dewdrops. In the wild the shrub grows through the dry forests and thorn scrub of the Argentine northwest, where the common name, roughly white tala, sets the plant among the talas, the spiny native trees and shrubs that give those woodlands their character.
Erythrina × bidwillii is one of the great show-stoppers among the coral beans, a bold hybrid between the Argentine cockspur coral tree, Erythrina crista-galli, and the southeastern native coral bean, Erythrina herbacea. From that crossing comes a plant with the size and drama of the South American parent and the toughness of the North American one, throwing long spikes of vivid, tubular scarlet flowers through the summer, far larger and more sustained than either parent alone.
This very rare aster, now placed in the genus Eurybia, is a true Florida endemic, native only to the moist pine flatwoods of the lower Apalachicola River. The plant is a botanical oddity: the clumping, foot-tall foliage is narrow, stiff, and grass-like, so unlike the leafy stems of an ordinary aster that a passerby might take the clump for a tuft of sedge. From late spring into early summer, slender flower stems rise above the leaves carrying clusters of inch-wide lavender-purple daisies, each ringing a small yellow eye.
The limequat was born of catastrophe. After the twin freezes of 1894 and 1895 laid waste to Florida's groves, Walter T. Swingle of the United States Department of Agriculture set out to breed citrus that could shrug off a cold snap, and in 1909 he crossed the sharp little West Indian or Key lime (Citrus aurantifolia) with the round Marumi kumquat (Fortunella japonica). Named and introduced in 1913 alongside a sister seedling called Lakeland, the Eustis limequat stands among the first successful intergeneric citrus hybrids, living proof that two separate genera could be wedded and still bear generous fruit.
Hamamelis virginiana does everything backwards, and that is the entire appeal. When the rest of the woods has shut down for the year, when the leaves are gone and nothing else is in flower, witch hazel chooses that exact moment to bloom: spidery yellow flowers, all thin crimped strap-like petals, scattered along the bare branches through late fall and into the cold. They carry a faint sweet scent on a mild day and they wait, patiently, for whatever gnat or late fly is still working, because almost nothing else is. This is the shrub that flowers when flowering makes no sense, and is all the more loved for the defiance.
Few flowers announce themselves the way white ginger lily does after dark. Through late summer and early fall, the tall leafy stems open dense terminal spikes of pure white flowers, each bloom shaped like a hovering butterfly with a small yellow-green stain at the throat, and each one throwing a rich, sweet perfume that carries across a warm garden in the evening air. The scent is jasmine-deep and unmistakable, the reason the flowers are gathered for perfume and personal adornment across the tropics.
Heimia salicifolia is an airy, fine-textured shrub that carries a surprising amount of history in a modest frame. Slender willow-like leaves clothe the arching stems, and from midsummer into fall small, bright yellow, five-petaled flowers open in the leaf axils all along the branches, each followed by a little dry seed capsule. The overall effect is light and gauzy, a soft yellow haze rather than a bold splash, and the plant grows fast and multi-branched into a rounded, four-to-eight-foot mound.
Hibiscus dasycalyx is one of the rarest wildflowers in the country, described only in 1968, and even then from a mere handful of sites in the bottomlands of east Texas, in Houston, Trinity, and Cherokee counties, along the Neches, Angelina, and Trinity rivers. The total wild population has been estimated in the low thousands. Whole seasons of botanical fieldwork across the Southeast have turned up fewer plants than a single good nursery bed.
Hypericum nudiflorum is the early riser among the St. John's Worts, a slender, upright shrub that opens golden flowers as early as May, often a full month ahead of relatives. The blooms carry the many-stamened brush typical of the clan, set against broad, light green, oval leaves that give the plant a softer, leafier look than the needle-leaved species.
Ilex glabra 'Leucocarpa' is the white-berried surprise among the inkberries, a native evergreen holly that trades the usual near-black fruit for berries of clean ivory white. On the ordinary inkberry the dark berries all but vanish against the deep green leaves, but here the pale fruit stands out cleanly and holds on the branches from fall right through to spring, a quiet, unexpected show in the winter garden.
Ilex paraguariensis is the holly behind maté, the caffeine-rich tea poured from a gourd and sipped through a metal straw across Argentina, Paraguay, Uruguay, and southern Brazil. As a plant, yerba maté is a broadleaf evergreen holly, a shrub or small tree with dark, leathery, serrated leaves, closely resembling the native dahoon holly, Ilex cassine, of the southeastern United States, and carrying the same small white flowers and, on female plants, small red berries.
Ilex 'Apollo' has one job in the garden, and does it superbly: pollination. A vigorous hybrid deciduous holly from the U.S. National Arboretum, crossing the Japanese winterberry, Ilex serrata, with the native American winterberry, Ilex verticillata, 'Apollo' was bred and released specifically as the male partner for the celebrated female 'Sparkleberry', and stands in equally well for 'Winter Red'.
Ilex verticillata 'Red Sprite' is winterberry shrunk to garden size and cranked up in intensity. Where much of the landscape fades to gray, this compact native holly turns into a beacon, the bare stems packed with heavy clusters of large, glossy scarlet berries that color in fall and cling deep into winter, a living ember at the pond's edge or against fresh snow.
Every winterberry covered in red is hiding a secret, and his name is 'Southern Gentleman'. Winterberry hollies are dioecious, male and female on separate plants, and only the pollinated females set the blazing red fruit the species is grown for. No male nearby, no berries. 'Southern Gentleman' is the male who makes the show possible, and asks for none of the credit.
Ilex 'Sparkleberry' is the aristocrat of the winterberries, a vigorous hybrid holly bred from the native winterberry, Ilex verticillata, and the Japanese winterberry, Ilex serrata, and introduced by the U.S. National Arboretum. The cross brought hybrid vigor and a heavier, longer-holding crop: tall, upright stems that shed their leaves in fall and blaze with bright red fruit, persisting so well that the berries often hang on into spring.
