Salvia coahuilensis
Common name(s): Coahuila Sage
Description: perennial; native to the Sierra Madre Oriental in the southern boundary of Coahuila, Mexico. Vigorous growth with aromatic foliage and blue-purple flower spikes from summer until first frost. Rare in cultivation.
Height: to 2 ft. Spread: to 2 ft.
Position: full sun and lean, well-draining soil
Uses: ornamental, to attract pollinators
Winter Hardiness: to 15 F and below
Distribution: Mexico (S. Coahuila)
Care: prune to 6 inches above the ground in spring (after all danger of last frost) to rejuvenate foliage. Adding a 1-2 inch layer of gravel around the base increases survivability and prevents crown rot. Cutting back spent blooms in summer will encourage more blooming but is not necessary. No fertilizer.
