This species is named for the large leaves, shaped like arrowheads. The species name, sagittata, references the zodiac sign Sagittarius, the archer. The leaves have a wrinkly appearance and are fuzzy on the undersides. The true attraction, however, is the abundance of spikes of true blue flowers, which in this area will appear late in summer and into fall. The long trumpet-shaped flowers have protruding stamens and are appreciated by hummingbirds. Arrow Leaf sage is native to the Andes Mountains of Ecuador and Peru. It requires full sun to flower, but tends to sulk on hot, humid days. This perennial is not hardy in the Chicago area, but cuttings can be easily rooted for the next summer.
