The California ash, also known as two-petal ash, is a shrub or small tree that is quite different in appearance to many other ashes. The leaves have serrated edges and rounded tips, form in clusters of 3 to 9 leaflets. The white flowers have two petals and hang in fragrant clusters. This is a very good plant for drought since it has very low water needs.
Emerald ash borer has not yet affected the California ash in its native range. However, there is evidence the beetle has traveled as far west as Colorado and is likely to eventually reach the West Coast.
