Short-lived perennial that grows from 1 to 3 feet tall during the warm season. Clusters of small yellow flowers bloom from August to October followed by a brown, hairy seed with chaffy scales. Broom Snakeweed contains saponin, so it’s poisonous to all livestock except goats. The plant absorbs selenium, so it’s commonly used for reclamation and mines. Prefers partial sun and dry soils; drought tolerant.
