The difference between Sophora japonica and Robinia pseudoacacia

1. Difference of blades

The leaves of Sophora japonica are alternate, with 7-19 leaves forming pinnate compound leaves, which are elliptical to ovate-oblong, about 3-6 cm long, dark green in color and shiny. The leaves of Robinia pseudoacacia are usually opposite, elliptical, egg-shaped or oblong, smaller than the former, with a rounded or concave tip and a small pointed tip, a rounded to broadly cuneate base, green on the upper side and gray-green underneath.

2. The difference between flowers

The inflorescence of Sophora japonica is drooping and red in color. 200-500 flowers can bloom at the same time, and the fragrance is very strong. Robinia pseudoacacia has spike-shaped inflorescences, its bracts fall off early, and are white in color. Robinia pseudoacacia flowers are edible.
