Avicennia germinans (Black Mangrove)

Native along coasts from the southeastern United States through the Caribbean and tropical Americas, and from western tropical Africa to Angola, this evergreen tree grows in tidal mudflats and estuaries. In Florida, it can reach about 50 feet tall. Pencil-like roots rise above the mud, supplying oxygen to the underground roots when exposed to air. Leaf glands excrete excess salt, often leaving visible crystals. Its fragrant white flowers provide nectar for mangrove honey. Seeds begin germinating while still attached to the tree, and the developing seedlings can disperse with tides and currents. Photographed in Florida.
