Pecan

Large deciduous nut tree native to the Mississippi River valley in the USA. Gets very large (15-30m) and needs ample space. Produces thin-shelled nuts with rich, buttery kernels. Needs warm summers, cold winters, and LOTS of water. Cross-pollination between varieties is essential for nut set. Long-lived (100+ years) but slow to reach full production (8-12 years). Pecans do surprisingly well in Australia's irrigated inland zones.
