This tree is native to eastern Asia, especially China and Japan. Others common names include Chinese pagoda tree, Styphnolobium japonicum, Japanese pagoda tree, and Chinese Scholar.

Chinese Scholar Tree or Japanese Pagoda Tree A native of China, this medium sized tree grows to 65 feet in height, usually with a broad round crown.  It has a rapid growth rate and tolerates city conditions, heat, and drought. When grown in a yard, the Japanese Pagoda Tree can reach a height ranging from 50 to 75 feet; however, when grown along the road in compact soil, it only grows to 30 or 40 feet. Sophora has a height and spread of from 40 to 60 feet. It is hardy in zones 4 to 8  and prefers an open, sunny location.  

Bloom This tree begins to bloom when 10 to 15 years old. In late summer and early fall, 10- to15-inch upright panicles of mildly fragrant, creamy-white, pea-like flowers are produced at the ends of branches and live about a month.

Seeds Flowers are replaced by ornamental yellow seed pods, 6 to 8 inches long, which persist well into the winter and resemble strings of beads.

Bark The young bark is pale gray, becoming furrowed into fibrous, interlaced, scaly ridges.
