A moderately growing cultivar that is striking because of its twisted branches. Produces a tree 10 - 15 m high with a broad, ovoid to oval crown. Grafted on a high stem, but sometimes also on a low stem to produce a somewhat shrub-like manner of growth. A multi-trunked tree then develops later. The thorny branches grow in remarkable curves; young shoots often grow like cork-screws. The more or less hanging leaves are also somewhat twisted. Flowers appear only occasionally, only on old trees. Sensitive to strong winds. It is a valuable park tree that is used particularly for its winter silhouette. Winter hardiness zone: 5a
With its tortuous and spirally twisted branches Robinia pseudoacacia 'Tortuosa' provides an exceptionally
characteristic winter silhouette at a later age.
