Wax Myrtle (Morella cerifera)

Wax Myrtle (Morella cerifera)

Wax Myrtle is one of Louisiana’s most versatile and ecologically important native shrubs — an aromatic, fast-growing evergreen that fixes nitrogen, feeds birds, and defines the character of the Gulf Coast landscape. Its waxy blue-gray berries were used by early settlers and Indigenous peoples to make bayberry candles, and its fragrant leaves have long been used in Cajun and Creole cooking as a bay leaf substitute.

Traditional Uses

Wax Myrtle berries were boiled to extract wax for candle-making — a practice documented among both Indigenous peoples and European settlers of the Gulf South. The leaves were used as a culinary herb, insect repellent, and fever remedy in Cajun folk medicine. The bark was used as an astringent and for treating dysentery.

Ecological Role

Wax Myrtle is a nitrogen-fixing shrub that improves soil health. Its berries are a critical fat-rich food source for migratory birds, particularly yellow-rumped warblers, tree swallows, and eastern bluebirds. It provides dense nesting cover and is a larval host for red-banded hairstreak butterfly.
