Hyacinth Bean

The Hyacinth Bean is featured on the arbor in the Monticello vegetable garden and draws countless questions from visitors every year. In the Garden Book in 1812 Jefferson mentioned, "Arbor beans white, scarlet, crimson, purple . . . on the long walk of the garden." This tender annual vine grows to twenty feet and produces attractive purplish-green leaves, showy rose-purple flowers and pods, and unusual black and white seeds. Although not mentioned by Jefferson, Hyacinth Bean was sold by his favorite nurseryman, Bernard McMahon, in 1804.
