| Description | Unlike most Arizona plants, button bush is primarily an eastern U.S. species with disjunct populations in wet canyons and mountains in Arizona and California. Within the state of Arizona this species grows in mountain ranges around Phoenix and Tucson, especially where there is semi-permanent water. Plants grow into a dense shrub with light green, waxy leaves. The blooms are made up of spherical heads of numerous tiny white flowers with long exerted styles. Because of its high water usage this plant makes the most sense for a greywater basin where the ground stays more or less moist year round. |
