Culture
Easily grown in average, dry to medium, well-drained soil in full sun. Tolerates drought, poor soils, and some light shade. Over time, plants form slowly expanding clumps with deep and extensive root systems, and should not be disturbed once established. Difficult to grow from seed and slow to establish. Plants take on more of a shrubby appearance and tend to open up after bloom. Trimming or shearing foliage after bloom helps maintain rounded plant appearance and obviates any need for staking, but eliminates the showy seed pods.
Noteworthy Characteristics
Baptisia alba commonly called white false indigo, is an upright perennial which typically grows 2-3’ tall and occurs in dry woods from Tennessee and North Carolina to Florida. It features small, white, pea-like flowers (to 1/2” long) in erect racemes (to 12”) atop dark flower stems extending well above a foliage mound of clover-like, trifoliate, bluish-green leaves (leaflets to 2” long). Blooms in spring. Flowers give way to inflated seed pods (to 1 3/4” long) which turn brown to black when ripe and have considerable ornamental interest. Stems with seed pods are valued additions to dried flower arrangements.
The genus name Baptisia comes from the Greek word bapto meaning "to dye".
Specific epithet means white.
Problems
No serious insect or disease problems. Sensitive to juglone. Tends to perform poorly when planted close to black walnut trees.
Uses
Borders, cottage gardens, prairies, meadows and native plant gardens. Effective in naturalized settings. Best as a specimen or in small groups.
