    Shrub from the SW US and NW Mexico with broom-like branches and tiny compound flowers. Dioecious (separate male and female plants are required to produce seed). Extremely drought tolerant, preferring rocky or sandy soil, often one of the first plants to colonize disturbed areas. Flowers attract all sorts of winged pollinators. A bit weedy and not generally used as a garden plant, but it can be somewhat controlled through pruning. Does not tolerate wet feet. To quote Wikipedia: "Most people try to get rid of this plant". Keep a male plant if your goal is to avoid it reproducing.
