Chamise
Adenostoma fasciculatum
  
About Chamise (Adenostoma fasciculatum) 23 Nurseries Carry This Plant Chamise or Greasewood, a member of the Rose family, is a flowering plant native to California and northern Baja California. This shrub is one of the most widespread plants of the chaparral biome, sometimes forming monotypic stands. It is an evergreen shrub growing to four meters tall, with dry-looking stick-like branches. The leaves are small, 4-10 millimeters long and one millimeter broad with a pointed tip, and sprout in clusters from the branches. The leaves are shiny with flammable oils, especially in warmer weather. It is said to be highly flammable but can be kept fire-resistant by occasional watering. The branches terminate in bunches of white tubular flowers five millimeters in diameter, with five petals and long stamens. Chamise is one of the best plant for anchoring a slope and resisting erosion due to its wide spreading and deeply penetrating roots. In maturity it develops a large burl from which it will resprout after fire or severe pruning. In the wild it is the host plant of a common root parasite, Chaparral Broomrape. There are three recognized Varieties: Adenostoma fasciculatum var. fasciculatum is found throughout the range of the species. Adenostoma fasciculatum var. obtusifolium is found only in San Diego and Orange Counties. Adenostoma fasciculatum var. prostratum, a low-growing form, is found primarily on the northern Channel Islands. A cultivar known as 'Black Diamond' (Adenostoma fasciculatum 'Black Diamond') is popular and widely available.To learn more about this species and its close relative, Red Shanks (Adenostoma sparsifolium), visit the Jepson Herbarium's YouTube channel and watch a short video:
