The apricot is a fruit-bearing tree, native to Armenia and China and spread to Europe and the Caucasus. It is classified with the plum in the subgenus Prunus of the Prunus genus. It is a small tree, 812 m tall, with a trunk up to 40 cm diameter and a dense, spreading canopy. The leaves are ovate, 59 cm long and 48 cm wide, with a rounded base, a pointed tip and a finely serrated margin. The flowers are 24.5 cm diameter, with five white to pinkish petals; they are produced singly or in pairs in early spring before the leaves. The fruit is a drupe similar to a small peach, 1.52.5 cm diameter, from yellow to orange, often tinged red on the side most exposed to the sun; its surface is usually pubescent. The single seed is enclosed in a hard stony shell, often called a "stone", with a grainy, smooth texture except for three ridges running down one side.
