A striking and fast-growing deciduous tree, Robinia × ambigua ‘Purple Robe,’ commonly known as Purple Robe Locust, is valued for its vibrant, wisteria-like clusters of fragrant, deep pink to purple flowers in late spring. Its feathery, bright green foliage provides dappled shade, and its drought tolerance makes it well-suited for tough landscapes, including urban plantings and dry climates.
