Rich colors of purple to blue double petaled flowers are just stunning on this 4-foot plant. Its blooms sit on long pedicals producing a waterfall-like effect with the cascading bloom heads. We usually see blooms in mid-summer here but can be earlier depending on your weather. We haven't grown this variety for long, but it's already become a favorite in the nursery with its double blooms. This plant was called 'Purple Tiers' when first introduced into the United States.
