Monkey Puzzle (Araucaria araucana)
Araucaria araucana is an evergreen tree growing to 1–1.5 m (3–5 ft) in diameter and 30–40 m (100–130 ft) in height. It is native to central and southern Chile, western Argentina. Because of the longevity of this species, it is described as a living fossil.
It is usually dioeecious, with the male and female cones on separate trees, though occasional individuals bear cones of both sexes.
It is often grown in the British Isles as an ornamental. However, it is now becoming popular as a food crop since it produces large edible nuts. The nuts are edible raw or cooked. Fresh nuts taste a little like a uncooked chestnut or maybe a fresh green hazelnut. Dried monkey puzzle nuts are more like a dried chestnut and are quite hard and dry. Dried nuts can be ground down to make a flour.
