Erect, unbranched stems (to 40” tall) arise from a large basal rosette. Leaves are lanceolate, undulating, and ‘crisped’ on the edge. Flowers are green, becoming rusty brown with age. The seeds are a shiny tan, and are encased in the tepals of the flower, which allows them to float so they can be dispersed by water. They also catch easily in the fur and feathers of animals, which also helps to disperse them.
