The acacia tree is tall, light-loving, deep-rooted and fast-growing. Its pinnately compound leaves are similar to those of the acacia, but the acacia's leaves are slightly transparent. The flowers of the acacia tree are pale yellow and can be cooked and eaten, as well as being used as an herbal medicine or dye. The pods, unlike those of other legumes, are gelatinous and shrink between the seeds to form a rosary, commonly known as "acacia rice", which is also a traditional Chinese medicine. Sophora japonica flowers in the late summer, and other tree species flowering period is different, so it is an important source of honey plants.
The acacia tree is a deciduous tree, 15-25 meters high. Pinnately compound leaves 15-25 cm long; leaf axis hairy, base expanded; leaflets 9-15, ovate-oblong, 2.5-7.5 cm long, 1.5-5 cm wide, apical acuminate and finely cornucopiae, base broadly cuneate, grayish-white below, sparsely pubescent. Panicles terminal; calyx campanulate, 5-denticulate; corolla creamy white, flag petals broadly cordate, shortly clawed, and with purple veins, wing petals keeled with slightly purplish margins; stamens 10, unequal. Pods fleshy, beadlike, 2.5-5 cm long, glabrous, indehiscent; seeds 1-6, reniform. Flowering and fruiting period September-December.
