Symphyotrichum chapmanii (formerly Aster chapmanii and Eurybia chapmanii) is a species of flowering plant in the family Asteraceae native to the Apalachicola River drainage basin of Alabama and Florida.[4] Commonly known as savanna aster, it is a perennial, herbaceous plant that may reach 30 to 80 centimeters (1 to 2+1⁄2 feet) tall. Its flowers have purple to blue-lavender ray florets and pale yellow disk florets. It is a wetland species and is of conservation concern.[5] It may be extirpated in Alabama.[1]
