The pussy willow is a shrub to small tree in Southern Canada and north central to Eastern United States; occasionally a small tree up to 30ft but usually it is a multi-stemmed shrub. Pussy willow is normally found in wet conditions where it can become vigorous and suckering but can also be found on some dryer sites.

Male plants can be especially good as a specimen, hedge or in a rain garden for winter interest; though shallow roots can invade spaces and make gardening difficult. In late winter to early spring, silk textured, gray furry tufts emerge from buds (which come before the leaves). The tufts are actually flower catkins and the males ones are larger and more attractive than those of the the females. They are a considered a sign of spring as they are the first willow catkins to appear. Twigs can be cut and put in water indoors to induce flowering then dried. To preserve the shrub shape, stems should be cut back every 3-5 years.

Male stamens are golden and female pistils greenish. The Leaves are dull, medium green, and glaucous underneath; bark is dark gray and scaly. Ecological benefits include food for wild fowl, songbirds, and mammals. It also attracts butterflies, native bees, bumble bees, and honey bees.
