Pussy Willow is typically found growing in moist to wet soils in meadows, swamps and along lakes and streams, but also will be found in some drier conditions. This is a dioecious species (male and female catkins appearing on separate trees) that is most often seen as a large multi-stemmed shrub to 6-15’ tall, but is less frequently found as a small tree to 30’ tall. Before the foliage emerges in late winter (March in St. Louis), male trees produce a showy display of catkins (1-1.5” long) that are pearl gray and silky. Female trees produce smaller, less attractive, greenish catkins. Male pussy willows are noted for producing ornamentally attractive silky pearl gray catkins on leafless stems in late winter to early spring. These catkins purportedly resemble the pads on a cat’s paw, hence the common name.
