Wachendorfia thyrsiflora

Wachendorfia thyrsiflora, the marsh butterfly lily, is a plant species of 0.6–2.5 m (2.0–8.2 ft) high when flowering, that has been assigned to the bloodroot family. It is a large to very large evergreen perennial plant with an underground rootstock with clusters of roots produced at the nodes. The rootstock has a distinctive red colour that results from so-called arylphenalenone pigments. The sturdy, entire and broadly sword-shaped leaves have laterally flattened and pleated leaf blades. The golden yellow flowers are set a dense cylindrical panicle on a tall firm stalk. Flowering occurs from spring until mid-summer.
