Coccoloba uvifera commonly known as sea grape, uva de playa or uvero in Spanish, and raisin bord de Mer in French is a small, low branching shrub or tree that grows up to 15m in height. It is a flowering plant from the Polygonaceae family, which also includes buckwheat. The plant is native to coastal beaches throughout tropical America and the Caribbean, including southern Florida, the Bahamas, Barbados, and Bermuda. Few of the popular common names of the plant are Bay Grape, Bow Pigeon, Caracas Kino, Coccoloba Kino, Columbian Kino, Hopwood, Horsewood, Jamaican Kino, Mangrove Grape, Platter leaf, Pigeon Wood, Sea Grape, Seaside Grape, Seaside Plum, Shore Sea-Grape, Shore Grape, South American Kino, West Indian Kino, Wild Grape, Wild Mangrove Grape and Wild Seaside Grape. The sea grape tree is wind resistant and highly tolerant of salt conditions. For this reason, many are seen planted along the beach edges in Barbados as they also aid in adding stability to these very beach edges. The male and female plants can be distinguished by the appearance of their flowers with the males showing dead flower stalks.
Plant description
Seagrapes are sprawling evergreen shrub or small tree that grows about 2–15 m high with a bole of 30–60 cm with spreading or sprawling branches and a sparse crown. The plant is found growing in tropical climatic conditions mainly in the coastal hammocks, coastal scrub, coastal grasslands, and beach strands. It is widely tolerant to most soils, provided they are well-drained. It grows well in sandy soil but usually grows faster and larger in more fertile soils. Minor element deficiencies may appear in calcareous soils. Barks are smooth grayish to mottled with patches of white, gray, and light brown bark that peels off in flakes, with reddish sap, the inner bark is light brown. Twigs are green and puberulent when young, grey at maturity, glabrous or pubescent.
Leaves
Leaves are alternate, short-petioled, large, leathery, glossy, dark green, broadly bean-shaped, with wavy margins, up to 15 centimeters long, 8 in (20.3 cm) in diameter with a reddish-colored primary vein extending from the base. The entire leaf turns red as it ages.
Flower
Inflorescences are 10–30 cm, puberulent or glabrous, pistillate pendent in fruit; peduncle 1–5 cm, glabrous. Pedicels are 1–4 mm, glabrous. The flowers are small, white, and fragrant with five petals and eight stamens and bloom mainly in spring but also occasionally throughout the rest of the year, with female and male flowers on different plants.
Fruit
The flowers on female plants are followed by globose to pear-shaped fruit about 3/4 inches in diameter. The fruit has the size of a large marble but a bit tougher than the ordinary grape and it has one large seed. The fruit remains green and hard for a long time but eventually one by one they change to their mature deep purple color when ripe. It is produced in large clusters resembling grapes. The edible pulp which varies from acid to sweet and insipid surrounds a single, large, pointed seed which may account for 2/3 of the fruit volume. Fruit normally ripens unevenly in individual racemes and readily drops from the tree. Most fruit matures during the summer, but in some years some fruit may mature in late fall because of late bloom. Fruit is produced only on female trees but a male tree must be present for pollination. Assurance of a productive female tree with good quality fruit needs vegetative propagation. The large tree generally produces several thousand fruits per season, more than enough for individual use.
History
The Plant is indigenous to Mexico, northern South America, the Caribbean and southern Florida. It is now found pantropically and has been introduced to Taiwan, Australia, and the Philippines. In its native tropical range from Argentina north throughout the West Indies and in Florida, it occurs on sandy coasts, coastal hammocks, coastal scrub, coastal grasslands, and beach strands. It thrives in full sun to partial shade. It is drought tolerant and highly tolerant of salt spray and salty soils as well as strong sun and wind. It is often planted as a windbreak near beaches and as a hedge. It is sensitive to frost.
