Description.
This shrub is quite variable in appearance, and there are a number of varieties. It may be a small, rounded patch ten centimeters wide or a sprawling bush up to two meters tall. It is an intricately branched, brambly plant having small woolly leaves scattered along its green to brown stems. The leaves do not persist long and leave behind a naked weedy form bearing very tiny flower clusters at nodes along the thin stems. Each cluster is less than three millimeters wide and holds white, yellow, or pink flowers.
