Facts About

Kentucky yellow-wood hails from the southeastern United States (hardiness zones 4-8) and is not regarded as native to New England. A member of the legume family, this tree produces showy, sweet-smelling white-yellow flowers that mature into long, slender pods. It is called "yellowwood" because it produces a yellow dye that imparts a distinctive yellow cast to the heartwood.
