Description
Mountain guava is a wild relative of guayaba, commonly known as guava (Psidium guajava). It can be distinguished by opposite and nearly round thick and leathery leaves that are 1½ -2¾ inches in diameter. They are thick/leathery and almost stalkless. Smaller flowers are located at the ends or at the sides of the twigs that are about ½ inch across. Their round fruit is about ¾ inch in diameter, with calyx lobes at their apex. The mountain guava flower color is green and white and blooms in the spring and summertime. The plant is evergreen and can grow in height approximately 2.4 to 3.7 meters (8–12 ft) tall. It was denoted in 1976 as a small tree that is capable of growing to 20 feet tall.
