Comments: This biennial was the All-America Winner for 1972. The plants have beautiful 4-5" double blooms with a superb color range and will bloom the first year if started indoors. Grows to about 4 1/2 feet, so it may require some support. While technically a biennial, this one seems to come back year after year.
