18" tall x 24-36" wide (seed propagated). Desert Purple Sage is a western native gem that puts on a dazzling display of pale-blue and purple flower spikes in late spring. Little known outside of the circle of native plant enthusiasts, it is a fast growing, heavy bloomer best suited to the hottest, most challenging planting sites. This small growing shrub has highly aromatic, silvery leaves that are both beautiful and resistant to browsing mammals. Plant it where the soil is fast draining and rocky, sandy or loamy in texture. This is an excellent companion plant for late spring blooming Beardtongues.
