Nice thick clumps that grow 10 inches tall and mounds 18 inches wide with white flowers that look like small Astilbe, The flowers are produced in abundance then dry to a reddish tint in late summer. These plants are great for their foliage texture which is like a soft fern. Long lived in moister retentive soils that are well draining but tolerant of dry soils were flower production will be less. Part shade. Blooms the third year.
