Robinia pseudoacacia 'Umbaculifera' is a fast growing deciduous tree with pinnate dark green leaves and a rounded growth habit. The dense habit gives a heavy shade beneath it. It has pendant racemes of fragrant white pea like flowers in spring and early summer. It is a hardy tree that likes a sunny position in a well drained soil. It is very frost tolerant and moderately drought resistant once established. It copes well with windy sites and poor soils. It can be pruned to a smaller size if needed for smaller areas.  Robinias are leguminous, meaning they fix nitrogen with their roots
