Attracts bees, beneficial insects and butterflies making it an excellent addition to pollinator gardens. Grows well with sun - mostly shade and even moisture - regular water. Does well in average, gritty, rich and well-drained soil. A good option if you're seeking something heat tolerant, humidity tolerant and verticillium wilt resistant.
