Associates

When Cypripedium candidum occurs in prairies this species is usually found with it along with Zizia aurea.

 Distribution

Central OH and southern Ontario west to MN and IA. Valeriana edulis occurs in the western cordilleran region from British Columbia to Mexico.

Morphology

Perennial to 1.2 m from a long stout taproot and branched caudex. Leaves thick, almost parallel-veined, densely ciliate; basal leaves linear oblanceolate, to 30 cm, entire or rarely with 1-2 basal divisions; cauline leaves pinnately divided into a few segments from a broad, flat rachis. Inflorescence elongate, terminal, paniculate; plants polygamo-dioecious; corolla of perfect or staminate flowers to 3.5 mm, that of pistillate flowers usually less than 1 mm; fruit ovate or ovate-oblong, 3-4 mm.

The flowers smell very nice. These caterpillars seem to think they taste good too. Valeriana edulis is similar but mostly glabrous and occurs in western North America.
