It has an upright, vase-shaped form with multiple stems. The leaves are compound and consist of small leaflets, typically 0.5 to 1 inch (1 to 2.5 centimeters) long. The foliage is bright green and turns yellow in the fall.
Flowers: Korshinsk Pea Shrub produces small, bright yellow flowers in late spring to early summer. The flowers are pea-like in shape and are arranged in clusters along the branches. They are attractive to bees and other pollinators.
Fruit: After the flowers, Korshinsk Pea Shrub develops small, pea-like pods that contain seeds. The pods are initially green and mature to a brown color. These pods persist into winter and can add ornamental interest to the plant.
