Baptisia Australis. False Indigo, or Blue Sophora, is a hardy perennial that grows three to five feet. From mid-spring to early summer the plant sends out nine to twelve inch flower spikes with purplish-blue one inch flowers. The plant likes full sun and is not particular about type of soil.
Seed can be sown in the spring but some have found it beneficial to sow in the fall and let the seed stay in the ground over winter.
Germination of False Indigo seed is slow and uneven. The plants will not blossom until they have been established for two to three years.
False Indigo has been grown in North America since 1758.
Heirloom seeds are collected from the gardens and grounds of George Washington's Mount Vernon and cleaned and packaged by hand.
