Huge roaming and dramatic Salvia for full sun and VERY well drained conditions. Rich soil sends this 6′ tall by 4′ wide perennial soaring. Large clusters of royal blue flowers each held in a jet black calyx. Great affect. Full sun to light shade with regular summer water. Dies out in heavy cold soils. Locate in a warm site. Spreads by underground runners. Loved by hummingbirds. Blooms July to October or later if its frost free. Do not cut back until new growth appears in spring. Dies completely to the ground with the first hard freeze. Mulch in colder zones.
