Rich, royal purple flowers about 3 inches wide with 5 petals over a long season. A gorgeous, open shrub that is worth coddling in a pot. Prune in late winter to control size; it will bloom on either this year's or last year's growth. In ideal, tropical outdoor conditions, this shrub can reach 10-20 feet tall and 6-12 feet wide and can spread via underground suckers, but it makes a wonderful container specimen in harsh climates with winter storage in a non-freezing greenhouse or sunroom.
