Pimenta racemosa aka Bay Rum Tree

Pimenta racemosa, the bay rum tree, is an evergreen in the myrtle family. Its native range spans the Caribbean and Venezuela. It grows on low forest slopes, including dry sites in Puerto Rico. Growers plant it across the tropics for scent, shade, and oil. It has also spread beyond gardens on some Pacific islands.

Garden trees reach about 40 feet [12.2 metres] tall. Their crowns spread about 20 feet [6.1 metres] wide. Another account gives 49 feet [15 metres] as a usual height. Exceptional trees reach 82 feet [25 metres]. The dense crown forms a narrow column or pyramid. Growth is slow, which helps it fit smaller spaces. Thin tan or pale grey bark peels away in flakes. This reveals a lighter layer beneath. The trunk may have shallow ridges and grooves.

The dark green leaves are thick, leathery, and fragrant. Their shape ranges from oval to broadest near the tip. Small white flowers grow in dense panicles from April to August. These showy clusters stand out against the dark leaves. The fleshy berries turn reddish brown to black. Each holds one to three seeds. Growers value the tree as a specimen and shade tree. A spot near a path makes the leaf scent easier to enjoy.

Give this tree full sun and loamy soil that drains well. It grows best with steady moisture and slightly acid soil. It suits USDA zones 10–12 and needs little routine care. A brief light frost may cause leaf damage. Harder frosts can kill branches or cause severe dieback. Growers can top or coppice trees to boost leaf crops. Seeds offer a straightforward way to raise new plants. Rust can attack young leaves, shoots, and flowers. Black rot can also cause cankers. Pests include caterpillars, whiteflies, thrips, weevils, and scale insects.

Leaves supply oil for perfumes, soaps, and bay rum products. Traditional medicine also uses the leaves and their oil. Reports describe leaves, bark, and dried green berries as flavourings. Leaf tea is another recorded use. Yet the same source warns against swallowing fruit, leaf oil, or bay rum. These conflicting reports do not establish safe home use. Food-use approval for the oil does not remove those warnings. Bay rum and oil compounds can also irritate skin.
