Wachendorfia thyrsiflora is a strong growing evergreen rhizomatous perennial, commonly known as redroot or bloodroot. The plant grows fan-like tufts of pleated fibrous and hairless leaves from the underground red rhizome.
A large, erect, sturdy and hairy flower stalk of up to 1,2 m tall appears around the end of winter. It bears a cylindrical panicle of golden-yellow, six-tepalled flowers and three equal stamens. There are sometimes (not always) small brown markings on the upper tepals, although some of the literature states that these are on the lower tepals. The blooming season of this plant is spring and early summer (Bean and Johns, 2005; Manning, 2009).
