Good to Know Aruncus | Walters Gardens 

This part shade-loving plant produces beautiful sprays of lacy, cream-colored flowers in late spring to early summer. It is very floriferous when it's in bloom, completely covering the deep green foliage. Goatsbeard is similar in appearance to Astilbe in the garden, but it is more drought tolerant. Though Aruncus tends to be a slow-grower the first couple of seasons, once it is established it puts on a fabulous show year after year. Make sure it has plenty of room to grow when you first plant it; transplanting this species is a very difficult task. This species is native to North America.
