Points of interest

  • The Kentucky Coffeetree is prized for its hard wood which has been used for cabinet work, fine furniture, interior finishes, door and window sills, fence posts and rails.

  • This species is also used as an ornamental landscape plant.  In winter its large pods rattle in the wind creating interest in the winter garden.

  • Native Americans used the plant for a variety of things. Pulp was believed to be treatment for everything from headaches, combating fevers, to use as a laxative and even to treat insanity.

  • The Omahas mixed the bark of the tree with gay feather and part of a pulverized buffalo-gourd and used it as an appetizer and a tonic.

  • Early settlers reportedly roasted the beans (seeds) to use as a substitute for coffee.     

  • Many parts of the plant are considered to be poisonous and apparently the roasting helps decrease the toxic nature of these parts.

  • Coffeetrees have no serious problems when it comes to insects or disease issues.
