A native plant to the Eastern half of North America for Canada down to Georgia and west to the Mississippi river. The beautiful blue flowers have been used to make a blue dye comparable to the dye made from the flowers of indigo. It is also a welcome addition to a butterfly garden where it provides nectar for butterflies and is a host plant for wild indigo duskywing caterpillars as well as several others. This plant is resistant to damage by deer
Blue false indigo is a member of the legume family. It can grow to be over three feet tall and two feet wide. It produces 1 inch blue flowers on 10 to 12 inch flower spikes in late spring or early summer. It grows best in full sun to part shade but tends to get a little floppy when it doesn’t get a minimum of six hours of direct sunlight. It forms tall clumps which are especially attractive planted next to wooden fences. The bright, indigo blue flowers are attractive when combined with yellow or white flowered perennials.
The best way to propagate this plant is to collect seeds in late summer as soon as they mature and sow them directly where you want them to grow. Cuttings taken in April or May will also root fairly easily if they are taken while the growth is still soft.
B. tinctoria, a yellow flowered species of Baptisia, is also native to the eastern USA and grows well in warm, sunny gardens.
