Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

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.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This species bears dome-shaped flower heads several inches across that are crowded with tiny, tubular amethyst or white flowers that look somewhat like the blooms of an allium. It has lance-shaped, toothed leaves in hues of cordovan purple or deep green brushed with plum highlights. It blooms over a long season. Though it is a perennial, blue throatwort performs wonderfully as an annual and blooms summer to fall. Plants grow to about 3 feet tall and wide.
