Salvia clevelandii (Sage) - 4 feet tall by 5' wide with aromatic gray-green foliage and profuse golf ball-shaped clusters of electric blue-purple flowers. The flowers arise from dark ruby red calyces that form in whorls along the top foot of each reddish stem tip - flowering commences in late spring or early summer and continues for about a month. Plant in full sun in a well-drained soil. This native chaparral plant will survive on very little to no supplemental irrigation but plants are more attractive if given an occasional deep watering, so long as the soil drains well. Hardy to at least 15 F.
