Bastard Indigo, the perfect gift for that special someone, flowers are generally purple pea things although pale blue or white is possible, on plants that can reach 4m in height.
A quick growing, elegant, multi stemmed, winter deciduous, leguminous shrub from eastern North America that is sure to draw comment from garden visitors. Small elliptical leaflets make up lacy foliage from which long spikes of bottlebrush-like, deep purple flowers wave languorously in late spring.In need of some water but otherwise very tolerant of heat and exposure.Irresistible to nectar feeding insects.
