California Yerba Santa
Eriodictyon californicum
  
About California Yerba Santa (Eriodictyon californicum) 11 Nurseries Carry This Plant Eriodictyon californicum is a species of plant in the Boraginaceae (Borage) family (formerly classified in the Hydrophyllaceae or Waterleaf family). It is found in central to northern California and Oregon, where it grows in several types of habitat, including chaparral and forest. It is a shrub growing one to three meters tall. The smaller branches and foliage are coated in a sticky resin and are often dusted with black fungi. The narrow, long leaves are somewhat lance-shaped and up to 15 centimeters in length. They have an odor generally considered unpleasant and a bitter taste, making them unpalatable to most animals. The inflorescence is a cluster of bell-shaped white to purplish flowers, each between one and two centimeters in length. It spreads by suckers. It has been used as a general purpose medicinal plant. When first described, the California Mountain Balm was placed in genus Wigandia, so its basionym is Wigandia californica.
