kentucky coffeetree - gymnocladus dioica
Common Name: Kentucky coffeetree
Scientific Name: Family: Fabaceae Genus: Gymnocladus Species: dioicus Hardiness Zone: 3 to 8 Height: 60 to 80 ft Width: 40 to 55 ft Description: Kentucky coffeetree is an excellent city tree. It is tolerant of most Minnesota urban conditions and doesn't have disease or insect problems. It has beautiful form when mature, especially if grown in open space. The peculiar, "stump-like" twigs are a noticeable feature. The female Kentucky coffeetree produces large seed pods that can be a nuisance but the males do not and are preferred for the urban areas. Seeds, leaves, and young shoots that are surrounded by the gelatinous matter contain a toxin that is harmful to humans, pets, and livestock, so seeds should never be eaten straight from the tree. However, the name "coffeetree" is used due to settlers using the seeds for a coffee substitute. Native Americans also used the roasted seeds for beverage and food. It is native to parts of Minnesota, though it fairly uncommon in the wild. References: Koch, K. "Kentucky Coffeetree". USDA Plant Guide. https://plants.usda.gov/plantguide/pdf/cs_gydi.pdf.
