This Canadian native plant is often used in formal rock gardens or perennial borders - especially in hot, dry sites. Further, it makes a very reliable groundcover when massed in sunny, hot, dry, hard to grow areas. This tolerance to dryness is quite interesting considering it can be found growing in wetter sites in the wide. Fern-like aromatic foliage produces swarms of showy, flat-topped, white flowers for months in the garden. Provides long lasting beauty for beds..
