Salvia 'Marine Blue'
Common name(s): n/a
Description: perennial; thought to be a hybrid of S. chamaedryoides. Vigorous growth with aromatic, gray-green leaves and dark blue flower spikes from summer until first frost. Requires fast-draining soil to thrive.
Height: to 2 ft. Spread: to 3 ft.
Position: full sun and lean, well-draining soil
Uses: ornamental, to attract pollinators
Winter Hardiness: to 5 F and below
Drought: adapted to 4 months of summer drought
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.
