Grows 6 to 12 in. tall, spreading rapidly by trailing, rooting stems; will cover a 2 to 4-ft.-wide circle in a year. Deep lilac buds open to 2-in.-wide flowers with a dark purple center; rays are lilac above (fading nearly to white by second day), deeper lilac beneath. Blooms intermittently all year, more heavily in fall and winter.
Needs well-drained soil. Does well near the ocean. Use as ground cover or bank cover; if it gets too tall or weedy, mow or cut back in midsummer. Also good planted at top of a wall or in a hanging basket.
