White false hellebore (Veratrum californicum) can be identified from the similar green false hellebore (Veratrum viride) by its spreading to ascending panicle branches and white flowers. The latter species has drooping panicle branches in the inflorescence and creamy green flowers. White-false hellebore can be found in vernally moist meadows in the mountains across central and eastern Oregon as well as in lower elevation meadows west of the Cascades and along the Pacific coast.
