Sassafras is a genus composed of
three species native to North America [1], China [1] and Taiwan [1]. The name sassafras is a Native American
name used by the Spanish and French in Florida in the middle of the 16th
century. In 1577, the use of sassafras by Native Americans was reported and in
1587, Sir Walter Raleigh brought it back to England from the Virginia Colony.
In the early 17th century (1602—1603), several ships were dispatched from
England to the colonies to collect sassafras roots; the colonists used the wood
to build forts. These forays were known as the Great Sassafras Hunts.

Distribution
Sassafras is
native to North America from Maine through Ontario, Michigan, Iowa, and Kansas,
to Florida and Texas.
The Tree
The tree can
reach a height of 90 ft (27 m) and a diameter of 5 ft (1.5 m). The leaves vary
in shape from simple (entire) to mitten-shape to tri-lobed on the same tree.
Sassafras produces greenish-yellow flowers in the spring and bright red,
yellow, and orange foliage in the fall. It has thick, dark red-brown bark that
is deeply furrowed. Trees are either male or female, although the flowers may
appear perfect. The fruits are olive-shaped to spherical, with a dark skin and
thin flesh. Sassafras is a pioneer species, the first to invade abandoned
fields. It spreads asexually by root runners, forming small groves of the tree.
Sassafras grows alongside persimmon, oak, sweetgum, dogwood, ironwood and
pawpaw.
The Wood
General
Sassafras
heartwood is pale brown to orange brown, resembling ash or chestnut; the
sapwood is a narrow yellowish-white. The wood is coarse-grained, straight,
brittle and soft, with a spicy aromatic odor. Sassafras is a ring-porous
species.

Working
Properties: Sassafras is easily worked and takes a finish well. It glues well
and holds screws better than nails.
Durability: Sassafras
is very resistant to heartwood decay in exposed, damp conditions, making it
good for fence posts and the sills of houses.
Preservation:
No information available at this time.
Uses: Lumber,
furniture, posts, fence rails and posts, kindling, boxes, cooperage (slack),
general millwork, small boats, oil from root bark, colonial dye (orange) from
bark.
Toxicity: No
information available at this time.
