The wood of the American yellowwood is indeed yellow. Bark from the yellowwood's roots was used to produce a yellow dye by early settlers to North America, while wood from the trunk was used to make gun stocks. The American yellowwood is in the pea family and produces fragrant flowers in early June, blooming heavily every two to three years. The flowers are proceeded by seedpods that closely resemble those of field peas. There are fewer than a dozen American yellowwood trees in Central Park.
