⭐ Core Definition: Prunus

Prunus is a genus of flowering trees and shrubs from the family Rosaceae. The genus includes plums, cherries, peaches, nectarines, apricots and almonds (collectively stonefruit). The genus has a cosmopolitan distribution, being native to the temperate regions of North America, the neotropics of South America, and temperate and tropical regions of Eurasia and Africa, There are about 340 accepted species as of March 2024.

Many members of the genus are widely cultivated for their sweet, fleshy fruit and for decorative purposes of their flowers. Prunus fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena ("stone" or "pit"). This shell encloses the seed (or "kernel"), which is edible in some species (such as sweet almonds), but poisonous in many others (such as apricot kernels). Besides being eaten off the hand, most Prunus fruit are also commonly used in processing, such as jam production, canning, drying, and the seeds for roasting.

👉 Prunus in the context of Peach

The peach (Prunus persica) is a deciduous tree that bears edible juicy fruits with various characteristics. Most are simply called peaches, while the glossy-skinned, non-fuzzy varieties are called nectarines. Though from the same species, they are regarded commercially as different fruits.

The tree is regarded as handsome and is planted in gardens for its springtime blooms in addition to fruit production. It is relatively short lived, usually not exceeding twenty years of age. Peaches were first domesticated and cultivated in China during the Neolithic period. The specific name persica refers to its widespread cultivation in Persia (modern-day Iran), from where it was transplanted to Europe. It belongs to the genus Prunus, which also includes the cherry, apricot, almond, and plum, and which is part of the rose family.

Prunus in the context of Cherry

A cherry is the fruit of many plants of the genus Prunus, and is a fleshy drupe (stone fruit).

Commercial cherries are obtained from cultivars of several species, such as the sweet Prunus avium and the sour Prunus cerasus. The name 'cherry' also refers to the cherry tree and its wood, and is sometimes applied to almonds and visually similar flowering trees in the genus Prunus, as in "ornamental cherry" or "cherry blossom". Wild cherry may refer to any of the cherry species growing outside cultivation, although Prunus avium is often referred to specifically by the name "wild cherry" in the British Isles.

Prunus in the context of Almond

The almond (Prunus amygdalus, syn. Prunus dulcis (Mill.) D.A.Webb, nom. illeg. non Prunus dulcis Rouchy) is a species of tree from the genus Prunus. Along with the peach, it is classified in the subgenus Amygdalus, distinguished from the other subgenera by corrugations on the shell (endocarp) surrounding the seed.

The fruit of the almond is a drupe, consisting of an outer hull and a hard shell with the seed, which is not a true nut. Shelling almonds refers to removing the shell to reveal the seed. Almonds are sold shelled or unshelled. Blanched almonds are shelled almonds that have been treated with hot water to soften the seedcoat, which is then removed to reveal the white embryo. Once almonds are cleaned and processed, they can be stored for around a year if kept refrigerated; at higher temperatures they will become rancid more quickly. Almonds are used in many cuisines, often featuring prominently in desserts, such as marzipan.

Prunus in the context of Cherry blossom

The cherry blossom, or sakura, is the flower of trees in Prunus subgenus Cerasus. Sakura usually refers to flowers of ornamental cherry trees, such as cultivars of Prunus serrulata, not trees grown for their fruit (although these also have blossoms). Cherry blossoms have been described as having a vanilla-like smell, which is mainly attributed to coumarin.

Wild species of cherry tree are widely distributed, mainly in the Northern Hemisphere. They are common in East Asia, especially in Japan, where they have been cultivated, producing many varieties.

Prunus in the context of Apricot

An apricot (US: /ˈæprɪkɒt/ , UK: /ˈprɪkɒt/ ) is a fruit, or the tree that bears the fruit, of several species in the genus Prunus. Usually an apricot is from the species Prunus armeniaca, but the fruits of the other species in Prunus sect. Armeniaca are also called apricots. In 2023, world production of apricots was 3.7 million tonnes, led by Turkey with 20% of the total.

Prunus armeniaca was domesticated in ancient times in Central Asia and China. Cultivation of the tree then spread across Eurasia and to North Africa and Japan. The fruit is consumed both fresh and dried. Apricots are used in dishes including cakes, tarts, and jam, and in savoury dishes, for example in stuffing. In Austria, they are the basis of Marillenknödel, sweet apricot dumplings.

Prunus in the context of Prunus subg. Cerasus

Prunus subg. Cerasus is a subgenus of Prunus, commonly known as the true cherries. Species of the subgenus have a single winter bud per axil. The flowers are usually in small corymbs or umbels of several together (occasionally solitary, e.g. P. serrula), but some species have short racemes (e.g. P. maacki). The fruit is a drupe and has no obvious groove along the side. The subgenus is native to the temperate regions of the Northern Hemisphere, with two species in North America (P. emarginata and P. pensylvanica), four in Europe (P. avium, P. cerasus, P. fruticosa and P. mahaleb), two in North Africa (P. avium and P. mahaleb), and the remainder in Asia.

The fresh fruits of sweet cherry (worldwide) and Chinese cherry (in China) are consumed raw. The fruits of some species such as sour cherry are used to make desserts, sauce, jam and wine. The seeds of mahaleb cherry are used to make mahleb. Many species are cultivated as an ornamental tree, known as cherry blossoms.
