Resembling the delicate Astilbe, Aruncus dioicus (Goat's Beard) is a great-looking perennial with highly attractive feathery plumes of tiny, starry, creamy-white flowers that rise well above the dark green foliage. Blooming from early to mid-summer, it should be noted that the male plants (with many stamens per flower) feature more attractive blooms than the female plants (3 pistils per flower). Once the flowers are less prominent, the handsome billowing mounds of fernlike leaves take over, extending the visual appeal through fall.
