Sulphur Flower
(Eriogonum umbellatum)

This compact perennial is native to the western U.S.  The dense basal leaves form tidy mounds that produce golden spherical clusters that are at home in flower beds as well as wildflower and meadow plantings.  Sulphur Flower is quite drought-tolerant, making it an excellent choice for xeriscaping in the western U.S.  In addition, it is ideal for pollinator conservation, and several butterfly species are found in association with it.  The leaves will turn bright red in the fall.
