- Description
-
Blue sage is a delicate herbaceous, clumping perennial in the Lamiaceae (mint) family native to South and Central United States.The genus name Salvia is derived from the Latin term salveo, which means ‘be well’ and refers to the plant's purported medicinal properties. Azurea refers to the sky-blue color of the showy two-lipped tubular flowers.
Plant blue sage in full sun to partial shade in sandy or shallow-rocky soil. It prefers moist soil as long as there is good drainage but tolerates occasional drought. Flowers appear from mid-summer to fall for long lasting interest in the garden. Cut the stems back by 1/2 in the late spring to promote fuller more compact growth as stems can flop over with the weight of the flower spikes and this occurs especially in organically rich soils. This plant is resistant to browsing by deer. Propagate it by division or seed.
Blue sage grows from 3 to 5 feet high and has showy blue flowers that attract bees and butterflies, so consider it for pollinator gardens. This native works well in the middle of perennial borders, prairie gardens, and open meadows. It is also at home tucked into a rock or cottage garden.
Insects, Diseases, and Other Plant Problems: No significant problems.
