Leaves are opposite or sub-opposite, odd-pinnately compound, 6-10" long with 11-21 leaflets. Leaflets are 1 to 1-1/2" long x 1/2" wide, oblong shaped. Leaflets slightly hairy on the underside. Tip can be slightly apiculate. Fall color is yellow in colder areas, but not seen here very often. Petiole base is slightly enlarged somewhat like Cercis.
Nice flower display on the ground near the end of the bloom time.
Stems are green, sort of grooved and often covered with a downy material.
The branching pattern is pretty interesting, especially from below. The branches seem to go in any direction they choose but it creates a beautiful pattern against the sky.
The foliage actually looks more like Robinia, but there are no stipular spines and the leaves are alternate.
