Arching whorls of feathery, smokey-purple flowers continue for much of the summer above nice looking gray-green, broad, heart-shaped leaves. It is best to cut them back to the ground after flowering to keep them tidy, prevent flopping, and encourage reblooming. This is one of the favorite plants for a hot, dry garden, even though it needs a little care to keep looking its best. Looks great with Happy Returns daylilies. The flowers blooms are attractive to butterflies and are deer resistant. Purple Rain provides long summer bloom to the perennial border, rock garden, cottage garden, wild garden or naturalized planting.
