Mexican plum

Description

Prunus mexicana, commonly known as the Mexican plum, is a North American species of plum tree that can be found in the central United States and Northern Mexico. Its native range stretches from Coahuila and San Luis Potosí north as far as Wisconsin and South Dakota, east to Georgia, Kentucky, and Ohio. Mexican plum is widely cultivated, such as on the west coast of the United States. Prunus mexicana is usually found on woodland edges or in open fields. It has a single trunk and reaches a height of 15–38 feet (4.6–11.6 m). It has dark green, simple ovate leaves, fragrant white or pale pink flowers, and dark grey bark banded with horizontal lenticels. Mexican Plums are adaptable to a wide range of soil pH and are drought-tolerant. They are hardy in USDA zones 7 to 9. Early in the spring it is covered with clouds of white fragrant flowers that are up to an inch wide. The dark red or purple fruit ripens late in the fall. It is eaten fresh by both animals and humans, the latter also making it into preserves. Prunus mexicana is very similar to Prunus americana, and they intergrade along a broad contact zone centered around Arkansas and Missouri. These intermediate individuals may be impossible to assign to a specific species. Prunus mexicana is included in the section Prunocerasus. Prunus is a genus of trees and shrubs, which includes (among many others) the fruits plums, cherries, peaches, nectarines, apricots, and almonds. Native to the northern temperate regions, 430 different species are classified under Prunus. Many members of the genus are widely cultivated for their fruit and for decorative purposes. 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 many species (such as almonds) but poisonous in others (such as apricots). Most Prunus fruit are commonly used in processing, such as jam production, canning, drying, and seeds for roasting. Members of the genus can be deciduous or evergreen. A few species have spiny stems. The leaves are simple, alternate, usually lanceolate, unlobed, and often with nectaries on the leaf stalk along with stipules. The flowers are usually white to pink, sometimes red, with five petals and five sepals. Numerous stamens are present.
