Growing Hints:

Purchase plants in summer while in bloom to ensure you get the color you want. Water regularly during the first season. Once plant is established it will be fairly drought tolerant. In warmer zones, cut back spent stems to encourage a second wave of flowers in late summer to early fall. Cooler zones will not have enough time for a second wave of flowers, but deadheading will prolong blooming period. Propagate in the spring by division and give plants a light application of an organic fertilizer. Cut stems back to 6 inches on plants in the spring to encourage bushy growth.
