Salvia microphylla var. neurepia
This native of the American Southwest and Mexico forms an evergreen shrub or shrubby perennial with dark, glossy leaves that are small (but slightly larger than most microphyllas) and softly toothed. It blooms off and on all summer, and again, more vigorously, in late summer and autumn, in blossoms of cherry-red. Its attractive foliage cloaks the plant to the ground, so it is well suited to the front of the border. It can grow to 4 feet tall and twice as wide.
