Purple Robe Locust
Robinia pseudoacacia ‘Purple Robe’
33 feet high x 25 feet wide
Open upright shape
Racemes of deep rose-pink pea-like flowers in late spring are the first reason to choose this tree, then add the overall tree shape with a wonderfully textured, dark-barked trunk and the bluish-green open canopy of pinnate, fernlike foliage. Tolerance of dry alkaline soil is good.
