This hardy perennial has small flowers that are reminiscent of scabiosa, in a lovely color range of blues, maroons, pinks, and salmons. The 3-4 ft. plant height is excellent for the back layer of perennial borders, and also makes an excellent cut flower. The long blooming season of Knautia (mid-spring to early fall) allows cut flower growers to reap up to 2 cuts per season.
