Live Oak (Quercus virginiana)

Live Oak (Quercus virginiana)

Live Oak is the soul tree of Louisiana — the great spreading evergreen oak of plantation allées, bayou margins, and coastal prairies whose massive, moss-draped limbs define the visual identity of the Gulf South more than any other plant. It is one of the longest-lived trees in North America, with documented specimens exceeding 500 years, and one of the most ecologically important trees of the coastal plain. To plant a Live Oak is to make a gift to the future.

Cultural Significance

Live Oak is the defining tree of Louisiana’s cultural landscape — the tree of plantation allées, Cajun homesteads, and coastal communities. Its wood is among the hardest and most rot-resistant of any North American tree, used historically for ship building, including the USS Constitution (“Old Ironsides”). Spanish moss (Tillandsia usneoides) drapes its limbs in the iconic image of the Louisiana bayou.

Ecological Role

Live Oak supports over 400 species of Lepidoptera larvae. Its acorns are consumed by wood ducks, mallards, wild turkeys, white-tailed deer, and squirrels. It provides critical canopy habitat for neotropical migratory birds and nesting habitat for bald eagles, ospreys, and great horned owls.

In the Cajun Heritage Garden

Part of the Jardin — Heritage Garden collection at Big Mamou Enterprises, Live Oak is more than a tree — it is a living monument to Louisiana’s landscape, culture, and ecological heritage.
