About White mangrove
Laguncularia racemosa, commonly known as white mangrove or buttonwood mangrove, is a species of mangrove that thrives in tropical coastal ecosystems. It is characterized by its oval, grayish-green leaves and small white flowers clustered in spikes. This plant is excellent for coastal stabilization and mangrove restoration, adding a robust and natural element to coastal landscapes.
Native range
Tropical and subtropical coasts of the Americas, the Caribbean, and West Africa.
Care tips
This species requires full sun and saline or brackish soils, tolerating immersion in saltwater. Watering should mimic tidal conditions, allowing for periods of inundation and exposure. The ideal substrate is a mix of sand, silt, and clay typical of intertidal zones. Avoid transplanting into freshwater environments, as it will not thrive outside its natural saline habitat.
