A date palm is a palm tree on which dates grow. A palm tree (Phoenix dactylifera) of western Asia and northern Africa and cultivated also in California, having featherlike leaves and bearing clusters of dates. Tree (Phoenix dactylifera) of the palm family, found in the Canary Islands and northern Africa, the Middle East, Pakistan, India, and California. The trunk, strongly marked with the pruned stubs of old leaf bases, ends in a crown of long, graceful, shining, pinnate leaves. The fruit, called the date, is a usually oblong brown berry. Dates have long been an important food in desert regions, and are the source of syrup, alcohol, vinegar, and a strong liquor. All parts of the tree yield products of economic value, being used variously for timber, furniture, basketry, fuel, rope, and packing material. The seeds are sometimes used as stock feed. The tree is grown as an ornamental along the Mediterranean shores of Europe. Its leaves are used for the celebration of Palm Sunday (among Christians) and the Feast of Tabernacles (among Jews). Date sugar, a product of India, is obtained from the sap of a closely related species, P. sylvestris
