The middle storey of the garden, built to last. Large shrubs bridge the gap between the canopy and the ground, giving height, screening, and year-round substance without the scale or wait of a full tree.
'Winterthur' is the garden aristocrat of the native smooth witherod, an upright, well-built deciduous shrub selected by the late Hal Bruce at Winterthur Gardens in Delaware and awarded the Pennsylvania Horticultural Society's Gold Medal, the Styer Award, in 1991. The glossy green leaves give the plant clean structure and coverage through the season, then turn deep burgundy and red in fall.
Few shrubs wear a name as plainly as this one. Odoratissimum is Latin for the most fragrant, the sweetest-scented, and sweet viburnum earns the superlative in late spring, when conical panicles of tiny white flowers open across the canopy and carry a soft, honeyed perfume on warm air. A member of the moschatel family, Adoxaceae, and a cousin of the elders and the arrowwoods, Viburnum odoratissimum ranges as a wild plant from the Himalayan foothills of India through Myanmar, Thailand, and Vietnam to China, Taiwan, Korea, and Japan, a broad Asian sweep that hints at the plant's easy adaptability in the warm garden.
Viburnum is the classical Latin name for the wayfaring tree, and prunifolium means plum-leaved, for foliage that could pass for a wild plum at a glance. The English names have piled up over the centuries: blackhaw, stagbush, stagberry, sloe-leaved viburnum, and in some counties nannyberry. The haw in blackhaw is borrowed from hawthorn, which the shrub resembles in flower and in fruit while being no relation at all.
Laurustinus flowers when almost nothing else does. From late autumn the flat heads are already formed and waiting, tight clusters of deep pink buds sitting on the ends of the shoots, and through winter and into spring they open a few at a time into small fragrant white flowers, so the shrub carries pink and white together for months. The leaves are lustrous and leathery, dark above and noticeably paler beneath, held densely enough that the plant works as a screen the whole year. What follows the flowers is stranger and better: ovoid fruits of a hard metallic blue, almost enameled, ripening slowly to black.
Some viburnums are grown for the eye and some for the nose; the Burkwood viburnums are firmly the latter. Viburnum x burkwoodii is a cross between the intensely fragrant Viburnum carlesii and the glossy evergreen Viburnum utile, first raised by the brothers Burkwood and their partner Skipwith at their nursery near Kingston-on-Thames in England in 1924. 'Park Farm Hybrid' is a sister seedling from that same celebrated work, selected for a bolder flower and a deeper bud.
A tough, glossy evergreen born of two Chinese parents and a Prague nursery. Viburnum x pragense is the cross of the leatherleaf viburnum, Viburnum rhytidophyllum, with the service viburnum, Viburnum utile, first raised by the plantsman Josef Vik at the Municipal Nurseries of Prague in 1955 and named for the city in 1959. The epithet pragense simply means of Prague, a rare instance of a garden hybrid carrying a birthplace rather than a botanist.
A superior selection of the ancient chaste tree, chosen for the size and color of the bloom. Vitex agnus-castus 'Shoal Creek' is a deciduous large shrub or small tree, native in the species to southern Europe and western Asia and long grown across the South for a long season of summer flower. The palmate, aromatic leaves have now and then been mistaken for those of cannabis, a passing resemblance that gives the plant a certain conversational charm.
A brand-new intergeneric hybrid, and a small horticultural triumph. Dr. Tom Ranney of the North Carolina State University research station in Fletcher succeeded in crossing two icons of the Southern flora: the legendary Franklinia alatamaha, the lost Franklin tree that has not been seen in the wild since the early 1800s, with the native loblolly bay, Gordonia lasianthus. The result is xGordlinia grandiflora, a bigeneric cross that carries the best of both parents.
Shiny Xylosma is sometimes listed as Xylosma senticosa. It is an attractive heat and drought tolerant evergreen shrub with glossy leaves about 3" long and 1" wide. It is much grown in California and the Southwest as a hedge, screen planting, or small tree. The greenish yellow flowers are not conspicuous but fragrant. This plant is uncommon in southeastern U.S. landscapes but has done very well here in our area. It should have a sunny or slightly shaded area with good soil and good drainage. This plant is native to eastern Asia.
A native tree that bites back, and can numb a toothache. Zanthoxylum clava-herculis, the toothache tree or Hercules' club, is a small to medium deciduous tree of the citrus family, native along the coastal Southeast from Virginia to Florida and Texas. The genus name Zanthoxylum means yellow wood, and the species clava-herculis, the club of Hercules, names the stout, spiny, club-shaped trunk that is the tree's signature.
