Prunus: the genus of plums, cherries, peaches, apricots and almonds

Characteristics

Typical features include simple leaves, solitary or clustered flowers with five petals, and fruit that is a fleshy drupe. Growth habit ranges from small ornamental shrubs to large fruit trees. Many species have showy spring blossoms that are culturally significant and widely planted as ornamentals.

History and distribution

The genus has a long association with human cultivation. Several species were domesticated in different regions: peaches and apricots in Asia, plums in Europe and Asia, and almonds in the Middle East and Central Asia. Wild and feral Prunus species occur across Europe, Asia and North America, and some have been introduced worldwide for fruit production and landscaping.

Uses and examples

• Plums — fresh eating, preserves and distilled spirits.
• Peaches — fresh fruit and canning industries.
• Almonds — edible seeds widely used as nuts and in oil production; botanically the seed of a drupe.
• Apricots — fresh and dried fruit, jams and culinary uses.
• Cherries — sweet and sour types used for fresh markets and cooking.

Taxonomy and notable facts

Prunus is taxonomically complex; botanists recognize a number of subgenera and sections that group closely related species. Hybridization and cultivar development are common in orchards and gardens. Many species are important economically for fruit, wood or ornamental value; others are used as rootstocks. Some Prunus parts contain cyanogenic compounds and should be handled or processed properly.
