Quick Overview:

This false indigo hybrid (B. australis x B. alba) is a shrubby perennial which typically grows 3-4.5′ tall. It was discovered as a chance seedling in a trial bed at the North Carolina Botanical Garden in the early 1990s. Features smoky violet, lupine-like flowers (from B. australis) and gray-green, clover-like foliage on charcoal stems (from B. alba). Flowers appear in mid-spring, opening up from bottom to top in erect but slightly arching terminal racemes (to 1′ long) which extend well above the foliage. Flowers give way to cylindrical, bean-like seed pods (to 2.5″ long) which have good ornamental interest and are sometimes used in dried flower arrangements. Attractive foliage remains effective throughout the growing season.   (Courtesy of Missouri Botanical Gardens Plant Finder)

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. This hybrid cultivar will not come true from seed and is best propagated from cuttings.   (Courtesy of Missouri Botanical Gardens Plant Finder)
