Water Chestnut, Malabar Chestnut, Guiana Chestnut, or Provision Tree is a deciduous tree native to Central America. Of the family Bombacaceae it is a large water-loving mid-sized tree that produces large multiple-seeded oblong fruit. The seeds are edible raw but normally roasted, tasting somewhat like chestnuts. The young leaves and flowers are cooked and used as a vegetable. Also known as Pachira aquatica, these trees will become quite large (to 140' tall and over 8' in diameter at the base). A very unusual tree, excellent for shade.
