Blue False Indigo
Native to eastern and southern U.S. Tolerate poor, sandy soils and take some drought. Blue-green leaves have three leaflets. Small, sweet pea–shaped blooms in early summer on tall, tapering spikes. Inflated seedpods that follow are attractive in dried arrangements. Clumps gradually increase, but don’t need division; also resent transplanting once established.Baptisia australis
