Comments: Dwarf Desertpeony is a small forb, relatively common in select areas where its herbage is slight with only a few leaves per plant. Dwarf Desertpeony, or Desert Holly as it is also often called somewhat resembles its big sister Brownfoot or Wright’s Desertpeony, Acourtia wrightii, and they are often found in similar areas. Their flowers are very similar and both are observed under the protection of bushes or trees. It has a pleasant fragrance reminiscent of violets.
