Blue false indigo (Baptisia australis), also known as blue wild indigo, produces large, spiky clusters of blue flowers in late spring to early summer. The bushy plants eventually reach 3 to 4 feet tall and wide. (If they start getting too big for their spot, you can shear them back by 1/3 to 1/2 as soon as the flowers fade to get more compact, bushier regrowth. This also prevents self-sowing.)
Beautiful in bloom and handsome in leaf, blue false indigo is a classic border perennial, but it’s equally at home in a meadow garden or naturalistic planting. It has tremendous value for pollinators, providing nectar for hummingbirds and butterflies, and pollen as well for bumblebees. It also serves as a host plant for several butterfly species. U.S. native. Full sun. Perennial; Zones 3 to 9.
Harvested in August 2020. At least 20 seeds.
