Veratrum insolitum is a stout, hollow-stemmed perennial growing from a thick rhizome in the clay soil of wet evergreen forests. The erect cornstalk-shaped plant bears several large green elliptical leaves decreasing in size higher up on the grayish stem. The large panicle inflorescence is packed with many off-white hairy flowers each just under a centimeter wide. There are six fringed tepals and six stout stamens, each with a club-shaped yellow anther. The fruit is a capsule 2 to 3 centimeters long which contains large winged seeds.Flora of North America, Veratrum insolitum
