Blue Wild Indigo (Baptisia australis) Rising 2-4 ft. high from a woody base, blue wild indigo is a bushy, robust perennial. Flowers are blue-purple and pea-like, congested in dense, upright, terminal spikes, 4-16 in. long. Leaves are divided into three leaflets. In late fall the plant turns silvery-gray, sometimes breaking off at ground level and tumbling about in the wind.
