These willows grow in dense thickets along streambanks throughout
the state. They seldom grow taller than about 8 feet. As with
all willows, the leaves are very narrow and have a very short
petiole.
The male and female flowers grow on separate plants. The individual
flowers are very tiny, but they occur in catkins that are an inch
or two long, and look somewhat like caterpillars. These appear on
the branches at about the same time as the earliest leaves.
