Prunus mexicana
Prunus mexicana, commonly known as the Mexican plum,[1] Inch plum, and Bigtree plum,[3] is a North American species of plum tree that can be found in the central United States and Northern Mexico. DescriptionPrunus mexicana has a single trunk, an open crown, and reaches a height of 15–38 feet (4.6–11.6 m).[3] It has dark green, simple ovate leaves 2–4.5 inches (5.1–11.4 cm) long and 1.25–2 inches (3.2–5.1 cm) wide.[3] In the early spring it is covered with five-petaled fragrant white or pale pink flowers 0.75–1 inch (19–25 mm) wide.[3] Its dark gray bark is banded with horizontal lenticels.[4][verification needed] The dark red or purple fruit ripens late in the fall.[5][6] 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.[7] TaxonomyPrunus mexicana is included in the section Prunocerasus.[8] Distribution and habitatThe native range of the species stretches from South Dakota east to Wisconsin, Ohio, Kentucky, and Georgia, and south to the Mexican states of Coahuila and San Luis Potosí.[1][9] It is usually found on woodland edges or in open fields. It is adaptable to a wide range of soil pH and is drought-tolerant. The trees are hardy in U.S. Department of Agriculture zones 5 to 9. EcologyThe fruit is eaten fresh by both mammals and birds.[3] UsesThe fruit is made into preserves, and the tree can serve as a rootstock for grafting on other plum cultivars.[3] Gallery
