Persea borbonia or redbay^[3] is a small, evergreen tree in the laurel family (Lauraceae), native to the southeastern United States. It belongs to the genus Persea, a group of evergreen trees including bays and the avocado. Persea borbonia has several common names including tisswood,^[3] scrubbay, shorebay, and swampbay.

Description

Persea borbonia can be present as either a small tree or a large shrub. It has evergreen leaves that are about 3 to 6 inches long^[4] with a lance shape. The leaves are arranged alternately and emit a spicy smell when crushed.^[5] The leaves vary in color from bright green to dark green. These trees are capable of producing fruit that is a small, blue or black drupe.^[6] Redbay is a perennial, with a non-herbaceous stem that is lignified.^[7] The tree can live for 80 to 100 years[1]

Distribution

Persea borbonia grows in the coastal margins of the southeastern United States. It is endemic to the lowlands of Texas, Arkansas, Louisiana, Florida, Mississippi, Alabama, Georgia, South Carolina, and eastern North Carolina. Small, isolated populations can be found in coastal Virginia, and near the Maryland and Delaware state line.^[8] It also grows in the Bahamas and is cultivated in Hawaii.^[9] It usually grows on the borders of swamp land.

Due to an invasion of redbay ambrosia beetle in the Southern United States the tree is slowly dying out. The beetle was discovered in 2002 near Savannah, Georgia and it carries a laurel wilt fungal disease that is responsible for killing redbays.^[10] However, foresters agree the species will likely not go extinct in the southeastern U.S. since it appears to rejuvenate to some degree on its own.^{[citation needed]}

Uses

The plant is not widely used now for medicinal purposes, however members of the Seminole tribe formerly used it as an emetic to induce vomiting.^[11] The dried-up leaves can be used as a condiment.^[12]

The wood is hard and strong and can be used to build boats, cabinets and for lining the interior of structures. The wood is not traded on a large scale so it is confined to the regions where P. borbonia grows.
