Fruit Features

The fruit of false Indigo is distinguished by its unique, puffy and inflated appearance, bearing resemblance to a bean pod. Anchored on a slender stalk, the fruit encapsulates several seeds which, upon maturity, range in color from yellow to a deeper brown. Each pod exhibits a sturdy, yet somewhat dry and papery texture. In terms of size, the fruit is modest, often measuring a few inches in length, making it a noticeable feature against the foliage. Crucial for identification, these pods persist on false Indigo after the blooming season, offering a characteristic visual cue for the species. While the exterior is predominantly green when young, it transitions to a tan or brown as it dries and matures.
