The apricot tree is a small tree with a dense, spreading canopy. Also known as the ansu apricot, Siberian apricot, or Tibetan apricot, its origin is not exact due to its extensive prehistoric history of cultivation, but it is almost certainly somewhere in Asia and commonly thought to be Armenia. In modern times, it is most heavily cultivated in the Middle East, Western Asia, Northeastern America, and Eastern China. Apricot trees are perennials, meaning that they can live for very long periods of time; apricots usually live between 40 and 150 years. The apricot is native to a continental climate with cold winters, but is somewhat versatile and can grow in more Medeterranian environments as long as they have a suffient dormant period. The apricot is quite cold-hardy, more so than most other drupes including the peach, and can withstand temperatures as cold as −30 °C.
