Aruncus is a genus of clump forming herbaceous perennial plants in the family Rosaceae. Botanical opinion of the number of species differs, with from one to four species accepted. They are closely related to the genera Filipendula and Spiraea, and are native to mountainous damp woodland in temperate regions of the Northern Hemisphere. Creamy white plumes of flowers are produced above veined and toothed leaflets.
Tragopogon is also known as "goatsbeard" but is not closely related.
Goatsbeard does well in USDA Plant Hardiness Zones 4-9 in almost any soil, in sun, or light shade. Set plants approximately 18 - 24 inches apart. To get new plants, divide clumps in spring or fall; otherwise clumps can remain undisturbed indefinitely.
