Quick Overview:

Developed by Dr. Jim Ault of the Chicago Botanic Garden, this is a selection from open-pollinated seed collected from a complex hybrid of Baptisia.

Solar Flare Baptisia has a unique flower color all its own.  From late spring into early summer, the pea-like blossoms open lemon yellow, then take on a rusty orange blush as they age.  Both yellow and orange flowers are present at the same time on the impressive 12-18 inch long spikes. The large, shrub-like plant has blue-green foliage and an upright vase-shaped habit.

Easily grown in average, dry to medium, well-drained soil in full sun to part shade. Best in full sun in acidic, somewhat poor soils. Good drought tolerance. Plant develops a large taproot and is best left undisturbed once established. Plants tend to open up after flowering and may need support as the summer progresses. Foliage may be cut back after flowering to form compact bushy plants which remain attractive for the remainder of the growing season without staking, however the showy seed pods will be lost if this is done. Plants usually take 3 years to establish, but are of easy culture thereafter.
