Description
"This perennial herb produces one or more erect stems 14 to 85 cm (6 in to 2 ft 9 in) tall.[2] They grow from a thick taproot 1.3 to 5 m (4 ft 3 in to 16 ft 5 in) deep that produces rhizomes. The inflorescence is a spike of several flower heads.[1] The heads contain several flowers which are usually purple, but sometimes white.[3] The fruit is an achene tipped with a long pappus of feathery bristles.[2] The plant reproduces sexually by seed and vegetatively by sprouting from its rhizome. This species is slow-growing and long-lived, with specimens estimated to be over 35 years old.[1]" - Wikipedia
