Monos Plum (Pseudanamomis umbellulifera) is a large shrub or small tree native to Puerto Rico, where it is known as Ciruelas. It is a relative of Eugenias and is rare in plant collections. Monos Plum thrives in full sun or semi-shade and requires regular watering and moderate fertilization. In cold climates, it is best to use container-grown trees and protect them from temperatures below 30°F in a greenhouse. Optimal temperatures for fruit setting range from 75-85°F.

The Monos Plum is a bushy grower that can reach heights of 15 ft and widths of 15 ft. It can also be trained into a small tree. Its small white flowers grow in clusters and are followed by large (2-3 inches) fruit with thin golden skin and sweet, juicy, aromatic flesh. There is usually one seed about ½ inch in size within the fruit. They are a good source of vitamins and minerals, including Vitamin A, Vitamin C, and iron. Monos plums can be eaten raw or used in jams, jellies, and preserves.

This plant is relatively hardy and can tolerate some frost. Mature plants can survive temperatures in the 30sF for a few hours, while small plants must be protected. Monos Plum can grow in a variety of soil conditions, including sandy and alkaline soils, and has a moderate growth rate. It can also be grown in a container due to its relatively slow growth and compact, bushy shape. Monos Plum makes a beautiful garden specimen and is a rare and collectible fruit tree.
