dwarf willow

A dwarf shrub, forming a low mat of creeping stems, each with two or three small, broadly oval to rounded leaves. Leaves are thin, slightly glossy green, with conspicuous veins and bluntly toothed edges. Small reddish flowers appear alongside or slightly after the leaves in spring; male flowers turn yellow as the pollen ripens. Flowers on female plants are followed by seed pods that turn red as they ripen
