The apricot (Prunus armeniaca) is a fruit-bearing tree native to China. It is related to the plum, and classified with it in the subgenus Prunus of the genus Prunus. The fruit (pictured here) appears similar to a peach or nectarine, with a colour ranging from yellow to orange and sometimes a red cast; its surface is smooth and nearly hairless. Apricots are stone fruit (drupes), and have only one seed each, often called a "stone".
