Yampah (Perideridia gairdneri), also known as Gardener's Yampah or Common Yampah, is a native perennial that spreads by seed. It has a tall, slender stem and basal leaves up to 10" long with many narrow, sub-divided lobes. It can grow on moist or dry sites. Yampah is in the same family as many poisonous plants, such as Water Hemlock. Fun fact, it has a carrot-like smell and Native Americans used the tuberous roots for food. Yampa is a Comanche word.
