Iris brevicaulis is the low, quiet member of a famous clan. One of the five wild species known collectively as the Louisiana irises, the plant carries broad blue to violet flowers on curiously kinked, zigzagging stems, so short that the blooms rarely clear the fan of sword-shaped leaves. Botanists call that back-and-forth habit fractiflex, and the trait gives the plant one of the common names, zigzag iris; the Latin brevicaulis, short-stemmed, records the same feature, while a third name, Lamance iris, honors the American horticulturist Lora La Mance.
Iris cristata is the iris scaled down for the woodland floor, a dwarf native barely six inches high that spreads into low, overlapping fans of bright green blades. In mid to late spring the mats light up with small flowers, an inch and a half to two inches across, in soft lavender-blue to violet, each fall stamped with a white patch and a raised orange or yellow ridge. That ridge is the crest that gives the plant both the Latin name cristata, crested, and the common name crested iris, and the feature sets the species apart from the bearded and beardless irises alike.
Among the wild irises of North America, Iris fulva is the one that broke the color rules. Where the family runs to blues, purples, and yellows, the copper iris opens in warm coppery red to burnt orange, a shade no other native iris offers, carried on slender stems in late spring and early summer with a soft, slightly drooping poise. The Latin fulva, meaning tawny or reddish-brown, records that unusual color, and the common names, copper iris and red iris, say the same thing more plainly.
A small crested iris with the carriage of an orchid and a quietly extraordinary biography. Iris japonica was named by Carl Peter Thunberg in 1794. Thunberg was a protege of Linnaeus and one of the only Western botanists allowed into Japan during the country's closed period, from 1775 to 1778, so much of what he brought back is, in a real sense, the first documented record of Japanese flora in Western science. The species had already reached Europe two years earlier, carried out of China by Thomas Evans of the East India Company in 1792. By the 1820s Pierre-Joseph Redoute, the same artist whose rose paintings turn up on every aunt's tea tray, was painting the plant under the older name Iris fimbriata in his Choix des plus belles Fleurs. A treasure of cultivated gardens for more than two centuries.
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.

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, the sweetspires, are graceful shrubs of the family Iteaceae, named from the Greek word for willow after their willow-like leaves. Itea oldhamii is a little-known evergreen sweetspire from Taiwan, a compact shrub with an unusual party trick: the juvenile leaves can be holly-like, edged with small teeth, while the mature leaves settle to a smooth, entire margin. In late spring the plant carries racemes of small white flowers over glossy evergreen foliage.
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, also known as white jasmine, is a climbing vine with delicate white blooms. This plant grows well in southern zones and performs best in full sun with support.
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 officinale var. grandiflorum, the Spanish or Royal jasmine, is the large-flowered, intensely fragrant jasmine of perfume and tradition, a semi-evergreen twining vine that opens clusters of pure white, star-shaped flowers whose scent is among the most prized in the plant world. Larger-flowered and more tender than the common poet's jasmine, this is the plant behind jasmine absolute, the costly essence at the heart of classic perfumery.

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.
