Sassafras trees grow from 1535 m (50120 feet) tall and 70150 cm (2.56 feet) in diameter, with many slender branches, and smooth, orange-brown bark. The branching is sympodial. The bark of the mature trunk is thick, red-brown, and deeply furrowed. The wood is light, hard and sometimes brittle. It can be used to make a serviceable bow if properly worked. All parts of the plants are very fragrant. The species are unusual in having three distinct leaf patterns on the same plant, unlobed oval, bilobed (mitten-shaped), and trilobed (three pronged; rarely the leaves can be five-lobed). They have smooth margins and grow 720 cm long by 510 cm broad. The young leaves and twigs are quite mucilaginous, and produce a citrus-like scent when crushed. The tiny, yellow flowers are five-petaled and bloom in the spring; they are dioeciously, with male and female flowers on separate trees. The fruit are blue-black, egg-shaped, 1 cm long, produced on long, red-stalked cups, and mature in late summer. The largest Sassafras tree in the United States is located in Owensboro, Kentucky.
