Dalea greggii
The Gregg's prairie clover, or indigo bush, is a sub-shrub with an average height of 4-9 inches and a spread of 2-4 feet. The shrub is mainly grown for its silvery, blue-green, delicately compound leaves, but in spring and early summer, it blooms with purple pea-shaped flowers.
Trailing Indigo Bush is a long-lived, durable, evergreen ground cover requires almost no maintenance. It forms a dense silvery mound of foliage, and blooms with fuzzy purple flowers in the spring and early summer, attracting bees. Tolerates reflected sun and tough conditions. Plant in well draining soil; susceptible to root rot with overwatering.
For rocky slopes and exposed sites in the Southwest, this plant is a good ground cover. It is primarily grown for its foliage, but it also blooms purple in the summer. The plant is well adapted to dry conditions.
