Facts about Guavaberry

Myrciaria floribunda, Guavaberry or more famously known as the rumberry is a small evergreen tree belongs to the myrtle family Myrtaceae. The plant is native to Caribbean and is now found growing wild in many locations including Central and South America, Cuba, Dominican Republic, Haiti, Jamaica, Puerto Rico, and on many islands in the Lesser Antilles. The guava berry has also been introduced to Florida, Hawaii, Bermuda, and the Philippines. The fruit which is often confused with guava is actually very different from it. Though it has the tanginess of guava, it is rather a close relative to Camu Camu. The size of the fruit is almost half to that of cherry and is similar to other drupes that contain a translucent flesh or pulp surrounding a stone which is the seed. Few of the popular common names of the plant are Guavaberry, Guava berry and Rumberry.

Guavaberries are the main ingredient in Guavaberry liquor, a sweet, spiced alcoholic beverage made with rum and cane sugar that is traditionally homemade and shared during special occasions in the Virgin Islands. Guavaberry liquor is considered to be the national liquor of Sint Maarten. The plant is harvested from the wild, mainly for local use of its fruit, but also for medicines and wood. It is a very attractive plant, it is often it also cultivated in gardens, both for its fruit and as an ornamental.

Plant Description

Guavaberry fruit is an attractive, very slow-growing shrub or small evergreen tree that normally grows up to 17 m (55 ft.) tall with a trunk diameter of 30 cm (1 ft.), though is more commonly 5 to 10 m (16 to 33 ft.) tall with a short trunk and low-branching habit, forming a densely leafy rounded crown. The plant is found growing in dry or moist coastal woodlands. The plant prefers a fertile, deep, humus-rich soil in a sunny position. Plants can succeed in a variety of soils, though growth is poor if the pH is high. The bark is light grey or pale brown, mottled and flaking, revealing orange-brown under-bark.

Leaves

The plant has evergreen, opposite leaves that are ovate, elliptical, or oblong-lanceolate, pointed at the apex. It is about 1 to 3 3/16 in (2.5-8 cm) long and 1/3 to 1 3/16 in (0.8-3 cm) wide. Leaves are glossy, slightly leathery, minutely dotted with oil glands. They are dull green on top and pale green underneath. They are arranged in pairs along the ends of the branches and remain on the tree throughout the year.

Flowers

Flowers are small and insignificant, funnel-shaped with four white petals on the edge along with many white filaments arising at the center. They are borne at the leaf bases, in clusters of a few and come into bloom in the rainy season.

Fruits

Fertile flowers are followed by spherical, tropical fruit roughly the size of blueberries, each around 1 cm (0.4 in) in diameter. Unripe berries are green, while mature berries can range from yellow-orange to deep purple depending on the variety. The outer skin is thin just like a grape. Each Guavaberry features a one or more central roundish seed, which is covered by a succulent, strongly aromatic yellow-orange pulp. Guavaberries are tannic with a tangy, bitter-sweet flavor and hints of nutmeg, allspice, and pine wood. The berries are found on the Guavaberry tree, which can grow to a height of around 18 meters. They ripen in the dry season, which corresponds with winter and the festive Christmas season in its native range.

History

The Guavaberry occurs wild over a broad territory–Cuba, Hispaniola, Jamaica, Puerto Rico (including Vieques), the Virgin Islands, St. Martin, St. Eustatius, St. Kitts, Guadeloupe, Martinique, Trinidad, southern Mexico, Belize, Guatemala, El Salvador to northern Colombia; also Guyana, Surinam and French Guiana, and eastern Brazil. It has been sporadically cultivated in Bermuda, rarely elsewhere, but, throughout its natural range, when land is cleared for pastures, the tree is left standing for the sake of its fruits. The plant was introduced into the Philippines in the early 1900’s and has been included in propagation experiments in Hawaii. There is a healthy fruiting specimen at Fairchild Tropical Garden, Miami.
