Showy mass in large garden; boundary plantings, big shrub borders, screening. In cooler winter areas, can be planted with evergreens so unattractive winter branches will be masked. Showy large shrub or small tree.

Rapid bushy growth to 20 feet high and 15 feet wide. Leaves divided into 5-13 toothed lance-shaped leaflets, 1-1/2 to 4 inches long, bright medium green.

Bell-shaped, bright yellow flowers, 2 in. across in large clusters, followed by slender pods 3-8 inches in length.

Much of wood may die back in winter, but recovery is quite fast in warm weather.

Abundant seed pods occur on fertilized plants. Cut faded flowers to prolong bloom; prune to remove dead and bushy growth.
