Additional Information

Gymnocladus dioicus is a large deciduous tree with strong winter character from the branches and bark. Drops pods (female trees) and twigs, frequently causing litter problem, thus eliminating the straight species as a good street tree. Seeds were once used by US settlers as a coffee substitute, however pulp and seeds are toxic when not properly and completely roasted.
