'''Prunus''' is a [[genus]] of [[tree]]s and [[shrub]]s, including the [[plum]]s, [[cherry|cherries]], [[peach]]es, [[apricot]]s and [[almond]]s. It is traditionally placed within the [[rose]] family [[Rosaceae]] as a [[subfamily]], the [[Prunoideae]] (or [[Amygdaloideae]]), but sometimes placed in its own family, the [[Prunaceae]] (or Amygdalaceae). There are several hundred species of ''Prunus'', spread throughout the northern temperate regions of the globe.

The flowers are usually white to pink, with five [[petal]]s and five [[sepal]]s. They are borne singly, or in [[umbel]]s of two to six or more on [[raceme]]s. The fruit of all ''Prunus'' species is a [[drupe]] with a relatively large "stone". Leaves are simple and usually [[leaf shape|lanceolate]], unlobed and toothed along the margin.

==Classification==
Some treatments break the genus up into several different genera, but this segregation is not widely recognised other than at the subgeneric rank. [[Integrated Taxonomic Information System|ITIS]] recognises just the single Genus ''Prunus'', with the incomplete list of [[species]] as shown in the box on the right.
*'''''Prunus'' subgenera:'''
**Subgenus ''Amygdalus'': [[almond]]s and [[peach]]es. Axillary buds in threes (vegetative bud central, two flower buds to sides). Flowers in early spring, sessile or nearly so, not on leafed shoots. Fruit with a groove along one side; stone deeply grooved. Type species ''Prunus dulcis'' (Almond).
**Subgenus ''Prunus'': [[plum]]s and [[apricot]]s. Axillary buds solitary. Flowers in early spring stalked, not on leafed shoots. Fruit with a groove along one side; stone rough. Type species ''Prunus domestica'' (Plum).
**Subgenus ''Cerasus'': [[cherry|cherries]]. Axillary buds single. Flowers in early spring in corymbs, long-stalked, not on leafed shoots. Fruit not grooved; stone smooth. Type species ''Prunus cerasus'' (Sour cherry).
**Subgenus ''Lithocerasus'': [[dwarf cherry|dwarf cherries]]. Axillary buds in threes. Flowers in early spring in corymbs, long-stalked, not on leafed shoots. Fruit not grooved; stone smooth. Type species ''Prunus pumila'' (Sand cherry).
**Subgenus ''Padus'': [[bird cherry|bird cherries]]. Axillary buds single. Flowers in late spring in racemes on leafy shoots, short-stalked. Fruit not grooved; stone smooth. Type species ''Prunus padus'' (European bird cherry).
**Subgenus ''Laurocerasus'': [[cherry-laurel]]s. Axillary buds single. Flowers in early spring in racemes, not on leafed shoots, short-stalked. Fruit not grooved; stone smooth. Mostly [[evergreen]] (all the other subgenera are [[deciduous]]). Type species ''Prunus laurocerasus'' (European cherry-laurel).

==Uses==
The genus ''Prunus'' includes the [[almond]], [[apricot]], [[cherry]], [[peach]] and [[plum]], all of which have [[cultivar]]s developed for commercial [[fruit]] production. The edible part of the almond is the seed; the almond fruit is a drupe and not a "[[Nut (fruit)|nut]]". There are also a number of species, [[hybrid]]s, and [[cultivar]]s grown strictly as [[ornamental plant]]s, usually for their profusion of flowers, occasionally for leaves and bark. These ornamentals include the group that may be collectively called ''flowering cherries''.

[[Pygeum]] is a herbal remedy containing extracts from the bark of ''[[Prunus africana]]''. It is used as to alleviate some of the discomfort caused by inflammation in patients suffering from [[benign prostatic hyperplasia]].

Because of their considerable value as both food and ornamental plants, many ''Prunus'' species have been [[introduced species|introduced]] to parts of the world to which they are not native. Many of the Old World species are grown for ornament or fruit, and have been planted throughout the world; and some have become naturalised beyond their native range.

''Prunus'' species are used as food plants for the [[larva]]e of a large number of [[Lepidoptera]] species - see [[list of Lepidoptera which feed on Prunus]].
