|A wonderful addition to the late summer or fall border. This subshrub has fuzzy, purple-pink and white flowers that go until frost. Superb when combined
with ornamental grasses, joe-pye weed and sedums. Treat as an annual unless you're in USDA Hardiness
zone 8b, where you might get lucky and have it over-
winter. Provide full sun and well drained soil. Cut
back hardy at end of flowering season and mulch well
if you expect it will over-winter.
