The tropics, grown against the odds. Sub-tropicals bring bold leaves, vivid flowers, and a whiff of the jungle to gardens well north of the frost line, thriving through a hot Southern summer and, with a little shelter, holding on through the cold.
Dianella tasmanica 'Variegata' is a strappy evergreen perennial grown above all for foliage: arching, sword-shaped leaves boldly striped in white and green that stay dense and upright through the season and lend crisp, year-round structure to a bed. In spring and early summer, airy panicles of small, star-shaped, blue to violet flowers rise on wiry stems above the leaves, followed by glossy, deep blue berries that gleam against the pale striping, an unusual and long-lasting ornamental touch that gives the plant a second season of interest.
Dicliptera suberecta is a member of the acanthus family, Acanthaceae, and hails from the grasslands of Uruguay and Argentina, a heritage that shows in a love of heat, sun, and lean soil. Gardeners know the plant by two names that between them tell the whole story: Uruguayan firecracker plant, for the volley of tubular blooms, and hummingbird plant, for the traffic those blooms draw.
A relic of the old Southern wilds, Erythrina herbacea, the coral bean, is a plant that commands attention, graceful yet defiant, wild yet refined. A legume native across the coastal Southeast, the coral bean shifts habit with the winter: in frost-free zones the plant grows as a woody shrub, branching boldly above the ground, while farther north the top dies down with the first hard freeze, only to rise again from a thick, gnarled rootstock when the heat returns, an emblem of Southern resilience.
The 'De Soto' coral bean is an extremely rare white-flowered form of the familiar southeastern native Erythrina herbacea, whose usual dress is fire-engine scarlet. Where the wild coral bean lights the spring with red, this selection raises the same slender, tubular spires in clean, cool white, a startling and lovely departure that Woodlanders introduced some years ago and is pleased to offer again.
Eucomis comosa 'Sparkling Burgundy' is the pineapple lily dressed for drama, a selection grown as much for the foliage as for the flowers. In spring the broad, strap-shaped leaves emerge a deep, glossy burgundy-red, the richest color of the season, then soften toward bronzed green as summer heat builds, holding a smoky, wine-stained cast that sets the plant apart from any ordinary green pineapple lily.
In the forests of the Himalayan foothills and across monsoon Asia grows a fig of ancient bearing, Ficus roxburghii, known to botanists today as Ficus auriculata and to gardeners as the elephant-ear fig. This is no dainty exotic. In the tropics the plant makes a bold small tree; in the American South, where hard frost cuts back the top, the fig returns from the root each year as a heroic perennial, with a presence as memorable as a live oak draped in Spanish moss.
Hong Kong Kumquat is an evergreen shrub with the smallest fruits of the true citrus. It is a great plant for containers or smaller spaces. The Chinese preserve the colorful orange raisin-sized fruits for spicy flavoring but it is grown chiefly as a novelty ornamental. It is hardy outoors here in Aiken, SC but not likely to be winter hardy in colder zones. As with all Citrus these cannot be shipped to Florida, Texas, Louisiana, California, Arizona, or California.
Fortunella obovata 'Changshou' is the Changshou kumquat, the sweetest and most generous of the kumquat tribe, whose fruit swells to the size of a ping-pong ball, far larger than the little oval kumquats most people know. Round to gently obovate, ripening bright orange, that fruit is eaten whole, skin and all, the thin rind sweeter and more tender than any other kumquat's. A compact, dense, thornless evergreen, the Changshou is as pretty in a pot as it is productive.
Grevillea rosmarinifolia is a fine-textured Australian evergreen, a rounded to semi-prostrate shrub whose narrow, deep green leaves look uncannily like rosemary, giving the plant both the species name and a handsome, needled presence the year round. The likeness is only skin-deep, for this is a member of the protea family, Proteaceae, worlds away from any herb.
Firebush earns the name honestly. From late spring until the first frost, the arching branch tips carry tight clusters of slender tubular flowers in hot orange-red, each one a narrow torch held out for the hummingbirds and butterflies that work the plant from morning to dusk. The foliage plays along: new leaves and stems flush bronze to burgundy, the veins stained red, so that even between flushes of bloom the whole shrub reads warm. Few plants pull in as much winged traffic through the heat of a southern summer.
This ginger relative is a tall herbaceous perennial spreading by rhizomes. Showy spikes of reddish flowers on terminals of tall plants with long corn-like leaves. It spreads to form colonies in rich moist soil in sunny or semi-shady areas. Woodlanders originally obtained this Asian native ginger as seed from Coimbra, Portugal.
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.
Hibiscus hamabo is a tall branching shrub reaching fifteen feet or more, wide and rounded, clothed in broad soft leaves that feel almost felted in the hand. Flowers come through summer in a clear light yellow, single and open-faced, five or six inches across, each one carrying a deep crimson blotch at the throat that pulls the eye straight into the center. Individual flowers last a day, as hibiscus flowers do, and are replaced steadily for weeks. Autumn brings a second act that catches most people by surprise: the leaves turn red before dropping, which is not something the genus is generally known for.
Woodlanders has long championed hardy citrus, the trifoliate hybrids that push oranges and their kin well beyond the usual citrus belt, and 'Benton' is one of the toughest of the group. The plant is a citrange, a deliberate cross between the sweet orange, Citrus sinensis, and the hardy trifoliate orange, Poncirus trifoliata, that legendary deciduous, thorny survivor of cold-country citrus breeding. The name citrange simply fuses citrus and orange, and the hybrids inherit the trifoliate orange's remarkable cold tolerance.
Woodlanders has long led the way in offering cold-hardy citrus, the kinds that carry fruit well beyond the usual citrus belt, and Ichang Lemon is a favorite of the group. The plant grows as a medium, evergreen small tree with large leaves on winged petioles and thorny branches, opens the fragrant white flowers typical of citrus in spring, and follows with very large, lemon-yellow, fragrant fruit.
Seen from across a summer garden, Ipomoea fistulosa could pass for one of the great perennial hibiscus, a big soft-wooded bush hung with pink funnels. Look closer and the flowers give the game away: these are true morning glories, five-petaled trumpets in shell to lavender-pink with a deeper throat, carried in loose clusters above broad, bright green leaves. Better known to botanists as Ipomoea carnea subspecies fistulosa, the bush morning glory breaks the family mold by climbing nothing at all, standing instead as an upright shrub six to ten feet tall.
Justicia brandegeana, the shrimp plant, is a subtropical evergreen shrub from Mexico, grown the world over for the curious, shrimp-like flower spikes that give the plant its name: arching, overlapping bracts in warm coppery orange, salmon, and rust, from which small white flowers peek like a shrimp's legs. The bracts hold their color for weeks, so a well-grown plant seems always in bloom.
The shrimp plant earns the name honestly. The arching flower spikes are built of overlapping bronze-to-pink bracts, each one curved and shingled over the next, so that the whole drooping cluster reads unmistakably as the tail of a boiled shrimp. This is the soft pink form, gentler in color than the coppery-salmon type most people picture, and out of the bracts slip the true flowers: slender, white, two-lipped tubes freckled with maroon at the throat.
The Lakeland limequat is a citrus lover's answer to cold: a compact, productive hybrid that pairs the hardiness of the kumquat with the bright, tropical punch of Key lime. One of three limequats bred by W. T. Swingle of the U.S. Department of Agriculture in Florida in 1909 and named for the town of Lakeland, this cross (Citrus x floridana) joins the West Indian, or Key, lime with the round Marumi kumquat (Fortunella japonica). The result carries intense citrus flavor on a plant that thrives well beyond the usual citrus belt.
