|Annual growing 18 to 36 inches. Leaves are medium green, large and palmate, with lance-shaped leaflets to 5 inches long. Grown for their brilliant display of blue, white, or pink sweet pea shaped 1 inch flowers on tall spikes in summer and early fall. Wonderful cottage garden additions, eye-catching when planted in large masses. Other than requiring good drainage, not fussy about soil. Can start from seed in winter or early spring.
