Blue false indigo is a large, showy, shrub-like plant with gray-green leaves and 10 to 12 inch medium blue flowers in May. The pea-like flowers are followed by black seed pods which are interesting enough to leave up over the winter. Reliable, drought-resistant and long-lived, blue false indigo provides a strong structural presence in a garden.
