Also called Rose-of-Sharon. A popular groundcover, with large golden-yellow flowers appearing throughout the summer and fall. Plants have upright stems of bright green leaves, forming a dense weed-proof patch. To encourage a bushy habit, pinch the growth tips in the spring for the first two to three seasons. Especially useful for stabilizing slopes. Excellent among shrubs and trees. Evergreen in mild winter areas. Drought tolerant once established. Space at 5 to 10 plants per square yard.
