Salix chaenomeloides, the Japanese pussy willow, is a fast-growing shrub or small tree native to Japan, Korea, and parts of China, long valued in East Asian gardens for the show the plant makes in the depths of winter. Well before the leaves break, the bare branches set fat, silvery-white catkins with a soft, velvety nap, the largest and most striking of any pussy willow, and the branches are cut by the armful for early-spring arrangements.
The willows gave the world its first painkiller. Willow bark, steeped by Greek and Native American healers alike for fever and ache, carries salicin, the compound nineteenth-century chemists refined into salicylic acid and, in time, aspirin, which still wears the genus name buried in the chemistry. This particular willow comes by a quieter trade. Salix koriyanagi is the Korean basket willow, the name meaning just that, long grown across Korea, Japan, and China for slender rods woven into baskets and furniture by hands that wanted something straight, supple, and strong.
Salix eriocephala, the heart-leaved or Missouri River willow, is a graceful native shrub, sometimes a modest multi-stemmed tree, of riverbanks and wet meadows across northern and eastern North America. The plant rises on several trunks clad in coarse gray bark, reaching roughly eight to a dozen feet in the garden and more in wild thickets, and the epithet eriocephala, meaning woolly-headed, points to the soft, silky catkins that give the willow much of its charm.
Salix integra 'Hakuro Nishiki', the dappled willow, is an elegant small willow grown above all for the show its new growth makes in spring. As the shoots unfold, the glossy leaves emerge splashed and mottled in pink and creamy white, so freely that the whole plant reads as a soft cloud of blossom-pink from a distance, before the variegation settles to green and white through summer. The Japanese cultivar name, roughly white-dappled brocade, catches the effect exactly.
Salix nigra, the black willow, is the largest native willow of North America and a common deciduous tree of Southern wetlands, but 'Webb' is a strikingly different, vase-shaped form that gathers those loose, streamside branches into a small, dense, upright tree. The habit sets the selection apart at once, tidy and shapely where the wild black willow sprawls, while keeping all the toughness and easy water-loving vigor of the species.
Salix tristis is a dwarf, gray-leaved native willow and one of the most surprising members of a genus most gardeners picture standing knee-deep in water. This small, tidy shrub was originally collected by Woodlanders in Jefferson County, Florida, where the plant grew in pine flatwoods on well-drained, even dry, sandy sites, the opposite of the streambank home most willows keep. The soft, grayish, woolly-hairy leaves and neat, low frame set the willow apart at a glance.
