What is Maritime Pine?
P. pinaster Aiton (previously named Pinus maritima Mill.) is a medium-sized pine growing up to 100 ft tall with bright red-brown, deeply fissured bark. It has stout needles occurring in pairs, and the plant produces oval cones 10 to 20 cm long. The tree is native to the western and southwestern Mediterranean regions but has rapidly naturalized to other countries, including the US, England, South Africa, and Australia. The largest man-made forest in the world, the 900,000 hectare Les Landes on the Atlantic coast of southwestern France is populated almost entirely by P. pinaster.
What is it used for?Miscellaneous uses
In 1535, a French explorer is reputed to have used tea made from the bark of the maritime pine to treat scurvy among his sailors when his ship became icebound. The name Pycnogenol is a trademark of the British company Horphag Research, Ltd. for a proprietary mixture of water-soluble proanthocyanidins derived from the bark of the European coastal pine, which grows along the coast of southwest France in Gascogne.
