General Care & Growing Tips:

These plants need full sun to ensure adequate flowering, and well-drained soils to prevent root rot.  Like most plants, they benefit from a 2- to 3-inch layer of organic mulch.  Light applications of fertilizer may also prove beneficial.  Deadheading spent flowers will keep plants looking neat and tidy and lengthen the bloom period.  Plants will be killed to the ground by freezing temperatures, but pruning back dead limbs during winter can increase cold damage.  Instead, wait to prune until just as the new growth begins to emerge in spring. 

Common Pests:

Generally a pest-free plant, although nematodes can be a problem.  Pesticide use on this plant should be avoided, particularly when in bloom because of the wide variety of beneficial insects attracted to the flowers.
