Prunus armeniaca, the most commonly cultivated apricot species, also called ansu apricot, Siberian apricot, Tibetan apricot, is a species of Prunus, classified with the plum in the subgenus Prunus.
Prunus armeniaca is a small tree, 8–12 m (26–39 ft) tall, with a trunk up to 40 cm (16 in) in diameter and a dense, spreading canopy. The leaves are ovate, 5–9 cm (2.0–3.5 in) long and 4–8 cm (1.6–3.1 in) wide, with a rounded base, a pointed tip and a finely serrated margin. The flowers are 2–4.5 cm (0.8–1.8 in) in 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, 1.5–2.5 cm (0.6–1.0 in) diameter (larger in some modern cultivars), from yellow to orange, often tinged red on the side most exposed to the sun; its surface can be smooth or velvety with very short hairs. The flesh is usually firm and not very juicy. Its taste can range from sweet to tart.
