Every collection has its unnamed treasures, and this gardenia is one of ours: a plant grown from seed gathered on Emei Shan, the great sacred mountain of Sichuan in southwestern China. The species has not been pinned down, but the plant is unmistakably a gardenia, upright in habit and clothed in long, narrow, glossy dark green leaves quite unlike the broad foliage of the common Cape jasmine.
Carolina jessamine is the twining gold of the Southern spring, native to the southern United States and honored as the state flower of South Carolina. An evergreen vine of easy grace, the plant clothes a fence or trellis in glossy, narrow leaves and, as winter loosens, opens a wash of fragrant yellow trumpets that scent the whole garden.
'Pride of Augusta' is the old double-flowered Carolina jessamine, a twining evergreen vine that turns the familiar Southern gold into something fuller and more lavish. Where the wild species opens simple funnels, this selection packs each bloom with extra petals, so the vine carries a long, generous show of ruffled, double yellow flowers, sweetly fragrant, from late winter into early spring.
Carolina jessamine is the state flower of South Carolina and one of the most beloved evergreen vines of the South, prized for the wash of fragrant yellow trumpets that opens the gardening year. 'Margarita' is the cold-hardy answer to that beauty, a selection that carries the same sweet-scented gold well north of where the species usually gives out.
Some plants elevate the familiar into the extraordinary, and Gordonia lasianthus 'Variegata' does exactly that, taking the quiet majesty of the native loblolly bay and dressing it in a silken fringe of cream. The glossy green leaves are edged in irregular strokes of ivory, as though touched by the brush of some moonlit painter in the pine woods, and the whole shrub glimmers softly through every season.
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 grandiflorus, the swamp rose mallow, is a magnificent native perennial of the southeastern United States, grown for enormous soft-pink blooms and broad, velvety, gray-green leaves. Rising to eight or ten feet on stout stems, the plant brings a lush, almost tropical presence to the summer garden, at home in a wetland but just as striking in an ordinary bed or beside a pond.
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.
Few native bulbs command a wet margin the way Hymenocallis liriosme does. From a basal fountain of arching, strap-shaped, glossy green leaves rise leafless scapes, each crowned with several large white flowers whose narrow segments splay outward like pale spider legs around a central membranous cup. The fragrance arrives at dusk, sweet and carrying, a signal to the night-flying moths that pollinate the blooms in late spring and early summer.
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.
The Indio mandarinquat is one of those happy accidents that citrus breeding throws up now and then, a natural cross between a mandarin (Citrus reticulata) and a kumquat (Citrus japonica) that borrows the best of both parents. From the mandarin come the size, the deep orange color, and the perfume; from the kumquat come the sweet, tender, wholly edible rind and a welcome measure of cold tolerance. The fruits hang like small golden lanterns against dark evergreen leaves through winter, oblong and glossy, and the whole tree carries a poise that belies how easy the plant is to grow.
Iris verna is one of those plants that feels like a secret, small, fragrant, and impossibly charming once noticed. Native to the pinewoods and sandy slopes of the eastern United States, this understated iris has been a spring companion for centuries, brightening forest floors long before gardeners thought to give the plant a place at home.
Itea virginica, the Virginia sweetspire, is a native shrub of the wetlands, streambanks, and floodplains of the eastern United States, from New Jersey to Florida and west to Texas. Sometimes called Virginia willow for the shape of the leaves, though the plant is no willow at all, the species is prized for arching, fragrant white flower spikes in early summer and for a fall display of orange, red, and burgundy that rivals far showier shrubs. 'Henry's Garnet' is the selection that made the species a garden staple, free-flowering, with six-inch white racemes and a deep maroon-purple fall color that gives the plant its name.
Itea virginica, the Virginia sweetspire, is a native shrub of eastern wetlands and streambanks, prized for arching, fragrant white flower spikes in early summer and a brilliant fall display of red, orange, and burgundy. 'Little Henry' is the dwarf of the clan, a low, mounded selection that reaches only about three feet, packing the fragrant flowers and fiery fall color of the full-sized sweetspires into a tidy, compact plant for smaller spaces.
Itea virginica, the Virginia sweetspire, is a native shrub of eastern wetlands and streambanks, grown for fragrant white flower spikes in early summer and a fall display of red, orange, and burgundy. 'Longspire' is the selection chosen for its flowers: a form that carries notably long, white racemes, arching sprays of small fragrant blooms that outdo the wild plant for length and presence in early summer.
Itea virginica, the Virginia sweetspire, is a native shrub of eastern wetlands and streambanks, grown for arching, fragrant white flower spikes in early summer and brilliant fall color. 'Sarah Eve' is the exception in the family, the first pink sweetspire: the small flowers are essentially white, but they are carried on rosy-pink pedicels that tint the whole arching raceme a soft, distinctive pale pink, a color no other Itea offers.
Jasminum beesianum, the red jasmine or Bee's jasmine, breaks the mold of a genus known for white and yellow flowers. This vigorous, semi-evergreen twining climber from the mountains of Yunnan and Sichuan carries small, star-shaped blooms in a deep rose to velvet-red, an unusual color among the jasmines, softly and sweetly fragrant, opening in late spring over slender stems and small, pointed green leaves.
Jasminum officinale, the poet's jasmine, is the classic hardy jasmine of old gardens, a vigorous twining vine hung with intensely fragrant white flowers through summer. 'Fiona Sunrise' is a gold-leaved form of that familiar plant, raised at Fromefield Nursery in England and registered under the cultivar name 'Frojas': the new leaves emerge a bright chartreuse-gold, lighting a trellis or fence, and soften to green as the season goes on, while the sweetly scented white flowers open from late spring into summer.
