The pH preference is an acidic to neutral (less than 6.8 to 7.2) soil.

Leaf Color    Green and silvery
This plant has attractive foliage.

Culture Notes
This plant may need staking to maintain its shrub-like form.  Baptisia will self-sow and the resulting seedlings can be transplanted.  Although slow-growing the first few years, the blue dye obtained from its seeds is used as an alternative to the dye of Indigo when shortened supplies warrant it.  The mature plant is difficult to transplant, because of a deep tap root.  Deadhead after blooming; Cut back to 6" in the fall; Remove dead foliage only in the spring.   Plants serve as hosts for butterfly larvae.  Often planted with: Helianthus, Hibiscus, Miscanthus, Pennisetum, Heliopsis, and Rudbeckia.

Use a wire cage or stake and twine for support if desired.  Although deadheading spent blossoms is preferable, you can leave blooms on this plant for decorative seed pods (good for seed collecting).
