Littletree Willow is widespread in interior Alaska and one of the most common willows there, forming dense thickets. The scientific name means like a little tree. Except for a few shrubby willow species rarely attaining tree size, this and Feltleaf Willow (S. alaxensis) are the only tree species native in Alaska that are absent from the contiguous 48 states. It is one of several species sometimes producing diamond willow; these trunks with diamond-shaped patterns caused by fungi are prized for carving into canes.
