Echinacea serotina, the narrow-leaved purple coneflower or blacksamson echinacea,[3] is a species of flowering plant in the family Asteraceae. It is native to the states of Arkansas and Louisiana in the United States.[4] The species is sometimes listed as being found only in Louisiana, but the type collection was made in Arkansas, part of Louisiana at the time.[5]
Echinacea serotina is very similar to E. purpurea but with stiffer, bristly hairs on the foliage.[3]
