Alabama snow-wreath is one of the Southeast's rarest native shrubs and one of the easiest to grow, a combination that ought to put the plant in far more gardens than it occupies. In spring the arching, thicket-forming branches foam with feathery white flowers, and the trick of them is that there are no petals at all: the show is pure stamen, dozens of white filaments per bloom spraying out against five small greenish sepals, like little bottlebrushes of light along the stems.
The olive is an evergreen Mediterranean tree, sometimes a very large shrub, with narrow leathery leaves gray-green above and silver beneath, and small fragrant white flowers carried in axillary racemes in late summer. Fruit ripened in dry climates is the source of commercial olives and olive oil. In the humid Southeast the olive has never been a dependable fruit producer, whatever the winter hardiness, and the honest advice is to grow one here for the silver evergreen structure and treat any crop as a bonus. There is now a commercial grove in south Georgia, so perhaps a suitable variety has been found, though the University of Georgia's own assessment of adaptability and productiveness in the state remains carefully undecided.
The olive is an evergreen Mediterranean tree or large shrub, the narrow leathery leaves gray-green above and silver below, the flowers small, white, and fragrant in axillary racemes in late summer. Where summers are dry, that fruit becomes table olives and oil. Where summers are wet, as here, the crop is unreliable and the tree earns a place for other reasons entirely: for the color of the foliage in low light, for the character an old trunk develops, and for the fact that an olive in a Carolina garden is still an unlikely and pleasing thing. A commercial grove has gone in down in south Georgia, which is encouraging, though the University of Georgia is still calling the question open.
The olive is an evergreen Mediterranean small tree or large shrub with grey-green leathery leaves and small, fragrant white flowers in axillary racemes in late summer. Fruit produced in dry climates is the source of commercial olives and olive oil. While the species is generally winter hardy in the warmer parts of the southeastern United States, the olive has not been a dependable fruit producer in our humid climate, and has never been readily available in the South. There is now a substantial commercial grove in south Georgia, so perhaps a suitable variety has been found; the question is more open than it was twenty years ago.
A true olive for the shade, Olea yunnanensis is the sort of plant that rewards the gardener who reads labels twice. The genus is the olive genus, kin to the ancient Mediterranean fruit tree and to the sweet olives and privets of the same family, yet this species hails from the mountains of Yunnan in southwestern China rather than the sun-baked hills of the Old World. The narrow, leathery, dark green leaves carry an unmistakable Osmanthus cast, glossy above and paler beneath, and build into a dense, rounded evergreen canopy that holds the year.
Osmanthus armatus, a rare gem from the evergreen forests of western China, brings both elegance and resilience to the garden. This large, multi-branched shrub is known for thick, lustrous, dark green leaves adorned with prominent marginal and terminal spines, reminiscent of holly.
'Sasaba' is the holly osmanthus taken to a theatrical extreme, grown less for flower than for the sheer drama of the leaf. Each dark, glossy, evergreen leaf is cut and incised into narrow, spine-tipped lobes that jut out in every direction, so that the whole shrub reads as a slow green explosion. The Japanese name says it well: sasaba means bamboo leaf, for the narrow, divided foliage.
Osteomeles schweriniae, the bone apple, is a refined evergreen shrub in the rose family, close kin to hawthorn, cotoneaster, and photinia, and a botanical rarity seldom seen in American gardens. The genus name joins the Greek osteon, bone, and melon, apple, a nod to the stony hardness of the little fruits, while the species epithet honors the German dendrologist Count Fritz von Schwerin. Native to the dry valleys and open slopes of Yunnan and western Sichuan in southwestern China, the shrub carries very small, ferny, pinnate leaves along dense, wiry, arching stems, giving a fine texture unusual among broadleaf evergreens.
Parrotia persica 'Lamplighter' is a rare variegated form of the Persian ironwood, grown above all for the foliage: each leaf carries a broad, irregular border of creamy white around a grey-green center, so the whole canopy reads as soft, dappled light through the growing season. New growth can flush pink and rose before the variegation settles, and the effect is luminous rather than loud, a tree that brightens a shaded corner the way a lit lamp does, which is presumably how the selection came by the name.
Passiflora incarnata alba is the rare pure white form of the native maypop, the wild passionflower of the American Southeast. The flower keeps all the improbable structure of the species, an intricate three-inch bloom with a fringed corona above a central column of stamens and styles, but drained of every trace of lavender: white petals, white sepals, and a white corona, luminous and cool against the deep green foliage. The effect is a ghostly, refined version of a familiar roadside wildflower.

This rare Penstemon is a very attractive perennial with deeply cut, fern-like leaves and tall spikes of pinkish-violet flowers, each two-lipped tube carrying the yellow-bearded sterile stamen that gives the genus the name beardtongue. The dissected foliage is not merely a nice feature; it is unique in the entire genus, and no other Penstemon anywhere in the world has leaves like these. Bloom comes in late spring on stems of a foot to two, held well above a low basal clump.
Phoebe cavaleriei is a broadleaved evergreen of the laurel family, and one of the handsomest of them. The leaves are leathery, four to seven inches long, oblanceolate to obovate, deep glossy green above and a pale greenish white beneath, so the whole canopy changes color as the wind turns the foliage over. Crushed, the leaves give off a pleasant spicy scent, which is the family signature and the reason bay, cinnamon, and sassafras all count as cousins. The bark is reddish brown with fine longitudinal striations while the young branches stay green. Flowers come between May and July, yellow to yellowish white and barely an eighth of an inch long, followed by round fruits about half an inch across seated in persistent tepals. Nobody grows this tree for the flowers.
Phoebe chekiangensis is one of a group of Chinese evergreens that could give the American South a whole new kind of shade tree. Upright and clean-limbed, the tree carries dense, leathery, dark green leaves much like those of the related redbay, glossy and handsome the year round, and grows at a steady pace into a small to medium tree of real presence.
This Phoebe is a broadleaf evergreen tree in the laurel family, Lauraceae, and a relative of the redbay and the avocado in the genus Persea. The genus Phoebe gathers more than fifty species of evergreen trees and shrubs across subtropical and tropical Asia, long known in China as nanmu and prized for hard, fine-textured, aromatic timber used in fine furniture and building since ancient times.
Photinia integrifolia is a handsome broadleaf evergreen, a small tree or large shrub of the rose family, widespread through the hills of southern and southeastern Asia, from the Himalayas and the Western Ghats of India east into Southeast Asia, yet virtually unknown in American gardens. A relative of the familiar Chinese photinia (Photinia serrulata), the species carries the same glossy, leathery foliage but with untoothed, entire-margined leaves, the trait behind the epithet integrifolia.
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.
Pinckneya is a large shrub or small deciduous tree with showy pink flowers that are not flowers at all. What carries the colour is a single enlarged sepal on some of the blooms, expanded into a soft rose-pink blade three or four inches long, so a tree in full display looks convincingly like a poinsettia that has escaped into a Georgia bog. The true flowers are smaller, greenish-yellow, tubular, and easy to overlook beside the bracts. The leaves are oval and four to five inches long, and the whole plant is loose and open rather than dense.
Pithecoctenium cynanchoides, the monkey's comb, is a vigorous, tendril-climbing vine of the trumpet-creeper family, Bignoniaceae, native to the warm woodlands and thickets of South America. Semi-evergreen in mild climates, the vine climbs by many-branched tendrils and clothes a support quickly in heart-shaped, three-parted leaves, the terminal leaflet often turned into a grasping tendril of its own.
A refined and rarely offered evergreen from New Zealand, Podocarpus acutifolius forms a dense, finely textured silhouette of short, sharp-tipped leaves that give the plant a crisp, architectural presence. Heat-tolerant and well suited to the southern United States when properly sited, this uncommon conifer offers structure, restraint, and year-round depth in the landscape.
Podocarpus macrophyllus, the yew pine, is a familiar evergreen conifer grown as a shrub or small tree across the southern United States, valued for dense, dark, strap-like leaves several inches long and a tidy, upright frame. 'Okina' is the variegated form, a relatively recent introduction from Japan, whose new growth emerges creamy white before settling to soft green.
