Comments: A small, deciduous tree with a broad, rounded habit. Typically grows in cultivation at a slow-to-moderate rate to a height of 20-30'. Features erect, narrow, spike-like clusters 4-6" long of fragrant, dull white, pea-like flowers which appear in late spring. Flowers are followed by flat seed pods 2-3" long. Compound, odd-pinnate, dark olive green leaves (7-13 leaflets each) are attractive in summer but produce no fall color. Coppery-bronze bark exfoliates on mature trees.
Best grown in average, medium moisture, well-drained soil in full sun to part shade. Prefers full sun. Adapts to a wide range of soil conditions.
