A low mound of small, ruffled blooms in deep purple that holds its color through our mild falls and into early winter. Rockin Purple shrugs off the cool snaps that send tender annuals packing, so you get weeks more display than you'd get from heat-lovers.

Plant in decent drained soil and six hours of sun. Deadhead spent flowers to keep new ones coming, or leave them alone for a tidy, rounded habit. A cheerful filler for front borders and edging work when you're tired of waiting on spring.
