Calycanthus 'Venus' is a white-flowered sweetshrub bred by Dr. Tom Ranney at North Carolina State University, drawing on three species at once: the Eastern Carolina allspice (Calycanthus floridus), the California sweetshrub (Calycanthus occidentalis), and the Chinese sweetshrub (Calycanthus chinensis, long known as Sinocalycanthus). The result is a deciduous shrub that carries the best of all three: hardiness, substance, and an unusual flower.
Camellia fraterna is a camellia stripped back to wild beginnings, a species from the hills of eastern China far removed from the big, blowsy blooms of the garden japonicas and sasanquas. Where those carry a few large flowers, this one covers slender, upright branches in a snowfall of small, single, white flowers, faintly pink outside and softly fragrant, that arch the stems with their sheer number. The small, pointed evergreen leaves and open, airy habit give the plant an easy, natural grace.
Most American gardeners know two camellias, the winter-blooming Camellia japonica and the autumn-blooming Camellia sasanqua, each in a hundred named forms. Camellia longicarpa belongs to a different and far less familiar company: the small-flowered wild camellias of section Theopsis, scarcely grown on this side of the Pacific. Woodlanders remains one of the few nurseries offering these lesser-known species to gardeners who want the wild plant rather than the show cultivar.
Fragrance is the rarest thing in a camellia, and Camellia lutchuensis is the great exception, a species grown less for the size of the flower than for the scent that rises from it. The blooms are small, single, and white around a center of yellow stamens, carried in profusion on a twiggy, airy shrub, and they release a sweet, sometimes spicy perfume unusual in a genus famous for having almost none.
Three things to know about this camellia. First, the tea-oil camellia is the most economically important non-tea member of the genus. China has cultivated Camellia oleifera for over two thousand three hundred years for the oil pressed from the seeds, a light, sweetish, monounsaturated cooking oil chemically close to olive oil (around eighty percent oleic acid in both), used for cooking, traditional cosmetics, hair tonics, and the historic rust-proofing of Japanese woodworking tools and chef's knives. Tea oil sits with olive, palm, and coconut among the four major woody oil crops on Earth. This is a working tree.
Few plants announce themselves the way Cestrum nocturnum does, and never by daylight. Through the afternoon the shrub keeps to a quiet, almost ordinary green, the slender branches arching and half-climbing, the small tubular flowers furled and unremarkable. Then dusk arrives, the cream-green trumpets open, and the night-blooming jasmine releases a perfume so far-reaching that it carries across a whole garden on still, warm air.
In the dead of winter, when the garden has given up on color and scent alike, Chimonanthus praecox quietly does the impossible. On bare, leafless branches, often in January and February, the wintersweet opens small, waxy, cupped stars of translucent pale yellow, each flushed at the heart with maroon, and from them pours a fragrance so rich and far-carrying that a single sprig will perfume a room. The Chinese name, la mei, the wax plum, catches the look of the petals exactly.

For a week or two in late spring, the Chinese fringetree disappears under snow. Chionanthus retusus var. serrulatus is a deciduous small tree of East Asia, native to China, Korea, and Japan, and the great show is the flowering: dense, lacy, fringed panicles of pure white, each petal narrow and strap-like, smothering the canopy so thickly that the foliage all but vanishes. The genus name says as much, from the Greek chion, snow, and anthos, flower.
The native fringetree is one of the great small trees of the southern spring. Chionanthus virginicus, a deciduous large shrub or small tree, often multi-stemmed, hangs the whole canopy with fleecy, drooping panicles of narrow white petals in spring, soft as torn paper and lightly fragrant, a look that earned the old country names old man's beard and grancy graybeard. On female plants the flowers give way to clusters of raisin-sized, deep blue-purple fruits that birds take quickly.
Choisya is a small genus of aromatic evergreen shrubs from the southwestern United States and Mexico, kin to citrus in the rue family, and Choisya 'Aztec Pearl' is the garden world's favorite of the tribe. The hybrid, a cross between Choisya arizonica and Choisya ternata, was raised by Peter Moore at Longstock Park Nursery in England, and the selection has proved hardier, more heat tolerant, and altogether easier in the garden than either parent.
Cinnamomum burmannii is the tree behind most of the cinnamon in an American kitchen, an evergreen of the laurel family whose fragrant inner bark, dried and ground, fills the great majority of the spice jars labeled simply cinnamon. Native to the highlands of Indonesia and across tropical Southeast Asia, this glossy-leaved tree is a cassia cinnamon, close kin to true Ceylon cinnamon, to the camphor tree, and to bay laurel, sassafras, and avocado. The whole plant is aromatic, from the leathery leaves to the spicy bark.
A rare evergreen tree from southern China, seldom seen in cultivation, Cinnamomum wilsonii belongs to the cinnamon and camphor clan, and the kinship shows in the glossy, leathery, dark green leaves, four to five inches long and marked with three bold veins that run nearly to the tip. Crushed or bruised, the foliage and bark give off the warm, spicy fragrance the genus is loved for. The Chinese name, chuan gui, places the tree in Sichuan and the mountains of the south, where the tree grows large and the aromatic bark has long been valued.
The rockroses bloom as if for a single day, and in a sense they do. Each papery flower of Cistus x purpureus lasts only from morning to evening before dropping, yet through late spring the shrub opens fresh bloom after fresh bloom, so the whole plant seems perpetually covered. The flowers are the draw: two to three inches wide, crushed-silk petals of pinky purple, each stamped at the base with a deep maroon blotch, a marking that earned the old garden name orchidspot rockrose. Rockroses are not roses, and are not related; the resemblance is only in the open, five-petalled face.
The Ponderosa lemon is grown for spectacle as much as for the kitchen. The fruits are enormous, often two to four pounds each, thick-skinned and gloriously bumpy, hanging like green-gold cannonballs among the glossy leaves. For all the size, the flesh is tart, juicy, and true lemon in flavor, and works in any recipe a regular lemon would, with the novelty of a single fruit that can fill a hand.
The Rangpur is not truly a lime at all, but Indian gardeners have used the fruit as one for more than five hundred years. Citrus x limonia, an old natural hybrid of mandarin and citron, bears small, round, deep orange fruits that look like tangerines and taste fiercely sour, with the aromatic bite that makes a fine lime substitute for cooking, cocktails, and marmalade. In India the fruit goes by surkh nimboo, the red lime, prized for exactly that intense, tart juice.
Among the very first of the citranges, Citrus 'Rusk' dates to 1897, when Walter Swingle crossed a Ruby orange with the tough, cold-hardy trifoliate orange, Poncirus trifoliata, in the great effort to breed citrus that could take a freeze. The result is a vigorous, tall-growing, notably hardy tree, evergreen to semi-evergreen, and dense with the distinctive three-parted trifoliate leaves.
Named for Walter Tennyson Swingle, the pioneering citrus breeder who spent his career crossing tender oranges with the iron-hardy trifoliate orange, the Swingle citrumelo is among the toughest citrus hybrids ever raised. A cross of grapefruit, Citrus paradisi, and trifoliate orange, Poncirus trifoliata, this vigorous, thorny, semi-evergreen shrub or small tree carries fragrant white citrus blossoms in spring, followed by pear-shaped yellow fruits about the size of a large orange.
Woodlanders has long led in offering citrus and citrus hybrids hardy well beyond the usual citrus belt, and the Troyer citrange is a classic of the kind. A cross of the Washington navel orange and the inedible but iron-hardy trifoliate orange, Poncirus trifoliata, the Troyer was raised in 1909 under the direction of the great citrus breeder Walter Swingle, and later named for A. M. Troyer of Fairhope, Alabama, where the tree first bore fruit, a nice southern footnote for a hardy citrus.
Woodlanders has long led in offering citrus and citrus hybrids hardy well beyond the usual citrus belt, and U.S. 119 is one of the most refined of the group. A complex USDA hybrid, a citrumelo crossed back with a sweet orange, the tree runs one quarter trifoliate orange, one quarter grapefruit, and one half sweet orange, a pedigree chosen to keep the toughness of the trifoliate while pushing the fruit toward genuine quality.
US-942 began life as a rootstock, bred by the USDA and released in 2010 after years of Florida field trials, a careful cross of the Sunki mandarin and the curious Flying Dragon form of trifoliate orange, Poncirus trifoliata. As a rootstock the record is stellar: compact, productive trees, strong resistance to Phytophthora and tristeza virus, and better tolerance of citrus greening than most, which is why growers across the citrus belt have come to trust the number.
