The horticulturist Scott Ogden, in Garden Bulbs for the South, sets the scene: the Japanese roof iris, Iris tectorum, is famous in the native country as a flower for planting on sod roofs, just as houseleeks are used on the cottage roofs of France. In gardens the silky green fans of leaves form large patches, a fine subject for the foreground of a shady border, and in April the ruffled, orchid-like blooms appear among the handsome leaves. In the common form these are a rich mottled blue with white crests; even lovelier, Ogden adds, are the white, yellow-crested blooms of the form offered here.

In gardens the silky green fans of leaves form large patches, a fine subject for the foreground of a shady border, and in April the ruffled, orchid-like blooms appear among the handsome leaves. This is the common form, in which the flowers open a rich mottled blue, veined and freckled toward the center, with white crests.
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.
Itea, the sweetspires, are graceful shrubs of the family Iteaceae, their name taken from the Greek word for willow. Itea yunnanensis is the Yunnan sweetspire, an evergreen species from southwestern China, close to the Chinese sweetspire but lower and more spreading, with more leathery, darker green leaves that are somewhat holly-like and toothed on juvenile plants and smooth-edged at maturity. In spring the plant carries slender four-inch racemes of small white flowers.
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 nudiflorum, the winter jasmine, is the great cold-weather bloomer of the genus, a deciduous scrambling shrub from western China that opens bright yellow, six-petaled flowers on bare green stems in the depth of winter, often from January into March, long before the leaves return. The name says as much: nudiflorum, the naked-flowering jasmine, blooming on stripped, leafless wands.

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.
Jasminum polyanthum, the pink jasmine or Chinese jasmine, is the most floriferous of the group, a fast, evergreen twining vine that smothers a support in late winter and spring with clouds of intensely fragrant white flowers opening from deep pink buds. Native to China, the plant is beloved wherever winters are mild for the sheer volume of bloom and a perfume strong enough to fill a garden or a room.
Some plants arrive at the nursery already wearing a mystery, and this jasmine is one of them. The stock was gathered high on a mountain pass above the White Water River in northwestern Yunnan, at roughly ten thousand feet, in the tumbled country of travertine terraces and snow peaks near Baishuitai that the Naxi people hold sacred. The collector, hedging as any honest collector will, noted only that this was probably a scandent shrub, and that guarded phrase is still the truest thing anyone can say about the plant's habit.
Juniperus communis, the common juniper, is the most widespread conifer in the world, a circumboreal shrub of northern latitudes and high elevations, and the source of the aromatic berries that flavor gin. The variety depressa is the low, ground-hugging North American form, a prostrate mat of prickly, blue-green needles. 'Hitchcock' is a Woodlanders selection of that low form, and hangs on one of the more remarkable botanical stories in the Southeast.

Juniperus rigida, the temple or needle juniper, is a graceful conifer of the windswept hills and old temple gardens of China, Korea, and Japan, distinctive for long, slender, sharply pointed needles that catch the light. 'Pendula' is the weeping form, unfurling those bright needles from arching, drooping limbs in a cascade of green that moves with the wind, a plant of quiet, sculptural dignity.
Juniperus virginiana, the eastern red cedar, is a tough, aromatic native conifer of eastern North America, found from Canada to the Gulf and famous for fragrant, moth-repelling wood and a pioneering habit on poor, dry, and abandoned ground. 'Lawrenceville' is a narrow, upright selection, a slender column of dense, dark evergreen foliage with short branches held close to the trunk, ideal where vertical form is wanted in a small footprint.

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.
Kadsura japonica, the Japanese kadsura, is an evergreen twining vine of the star-anise family, Schisandraceae, a close relative of the medicinal magnolia-vine Schisandra, native to the woodlands of Japan, Korea, and southern China. 'Fukurin' is the variegated form, glossy dark green leaves edged in a clean cream-yellow margin that lights up a shaded wall or fence and holds through the year.
Sheep laurel belongs to the heath family (Ericaceae), kin to the rhododendrons, blueberries, and pieris, and shares that family's love of cool, sour, peaty ground. The genus name honors Pehr Kalm, the Finnish-Swedish naturalist and student of Linnaeus who traveled the eastern colonies in the 1740s and sent plants and seed back to Uppsala; Linnaeus returned the compliment by fixing his pupil's name to this handsome American genus. The species epithet angustifolia simply means narrow-leaved, while caroliniana marks the southern form described from the Carolinas, distinguished by leaves softly gray-felted on their undersides.
