Flowers appearing in March at the joints of the naked wood, usually three together on very short stalks.

Native of eastern N. America; introduced in 1750. This is not a showy plant, and its yellow flowers are often injured by spring frost, but it is an interesting one. It is moisture-loving, and likes a deep soil to which some peat is added. A specimen in the Cambridge Botanic Garden attained a diameter of 9 ft. The remarkable toughness and flexibility of the shoots have been taken advantage of in several ways. In early times the American Indians used the bark for making ropes, and the twigs are still used in rural districts as tying material and for basket-making.
