Distribution and ecology

The species area extends from East Asia to the west of the Mediterranean, down to Spain. The Date-plum is native to southwest Asia and southeast Europe. It was known to the ancient Greeks as "the fruit of the gods" i.e. Dios pyros (lit. "the wheat of Zeus"), hence the scientific name of the genus. Its English name probably derives from Persian Khormaloo خرمالو literally "Date-Plum", referring to the taste of this fruit which is reminiscent of both plums and dates. This species is one candidate for the "lotus tree" mentioned in The Odyssey: it was so delicious that those who ate it forgot about returning home and wanted to stay and eat lotus with the lotus-eaters.[1]

The tree grows in the lower and middle mountain zones, the Caucasus, usually up to 600 m above sea level. In Central Asia, it rises higher - up to 2000 m. The net stands Rarely forms, usually grows with the frame, ash, maple and other deciduous species. It is not demanding on the soil, can grow on rocky slopes, but requires high light, so well cleaned of twigs, which makes its stately columned trunks look.

It is cultivated at the limits of its range, as well as in the U.S. and North Africa.
