The large, clustered, pure white flowers are like a zonal geranium. The glossy green leaves and the semi-trailing habit are like that of an ivy geranium. It blooms all summer long even in lower light conditions. Highly heat and drought resistant, plants grow best in a location with at least four hours of full sun. Calliope White is extremely well-branched, and its vigorous mounding habit is superb for hanging baskets, mixed containers, window boxes, and garden beds.
For best flower display, deadhead or remove spent blooms as needed especially after heavy rain.
