Salix tristis

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.

The name has a small taxonomic story of its own. Most botanists fold this plant into Salix humilis, the wide-ranging prairie willow of eastern North America, but J. K. Small, in his Manual of the Southeastern Flora, separated Salix tristis on the smaller size and a handful of technical characters, and the name has stuck in the nursery trade for these dwarf, gray, dry-ground forms. Whatever the rank, the plant is a distinct and collectible dwarf willow of the Southern flatwoods.

Like all the willows, the prairie willow carries salicin in the bark, the compound behind the family's long medicinal history and the distant chemical ancestor of aspirin. Indigenous peoples of North America used the bark and leaves of the small native willows to ease pain and fever, a tradition set out in the fields below. Silky little catkins open in earliest spring, before the leaves, feeding the first bees of the year.

In the garden Salix tristis makes a neat, small, gray shrub for a sunny, well-drained spot, a genuine rarity for anyone who wants a willow that will not demand wet ground. Use the plant at the front of a native or pollinator planting, in a dry sunny border, or in a sandy naturalistic bed, give full sun and sharp drainage, and enjoy the soft gray foliage and early catkins on a willow scaled for the small garden.
