The difference between kudzu and kudzu

1. Difference of blades

The terminal leaflets of Pueraria lobata are obovate, about 10-13 cm long, with a caudate-acuminate tip, a triangular base, entire margins, green above and gray below. The terminal leaflets of Pueraria lobata are broadly ovate or obliquely ovate, slightly wider than the former, about 7-15 cm long, and have a long acuminate tip.

2. The difference between flowers

Kudzu has racemose flowers about 15 cm long, usually clustered or arranged in panicles. The corolla is light pink in color and the standard petal is obovate. The pueraria has a raceme inflorescence that is longer than the former, up to 30 cm. The corolla is purple in color and has the same shape as the former, with the standard petal being obovate.
