Coco Plum
Chrysobalanus icaco
The Coco Plum (Chrysobalanus icaco), also known as the Paradise Plum or Icaco, is a tropical shrub or small tree belonging to the family Chrysobalanaceae. It is valued both for its edible fruit and its ornamental appeal in coastal landscapes.
• Native to tropical and subtropical regions of the Americas and western Africa
• Produces small, plum-like drupes that range in color from white to deep purple when ripe
• Widely cultivated as a hedge plant and for its salt-tolerant properties in coastal environments
• The fruit has been consumed by indigenous peoples for centuries and is used in jams, jellies, and beverages
• Native range extends from southern Florida and the Bahamas through the Caribbean islands to Brazil
• Also found along the western coast of Africa from Senegal to Angola
• Thrives in coastal environments including sandy shores, mangrove edges, and coastal scrublands
• The genus Chrysobalanus is part of the family Chrysobalanaceae, which comprises approximately 500 species across 20 genera, primarily distributed in tropical regions worldwide
Stem & Bark:
• Bark is gray to brown, smooth to slightly fissured
• Branches are often spreading, forming a dense, rounded crown
Leaves:
• Simple, alternate, broadly ovate to elliptic
• Approximately 5–10 cm long and 3–6 cm wide
• Thick, leathery texture with a glossy dark green upper surface and paler underside
• Entire margins; petioles short (~3–5 mm)
Flowers:
• Small, white to greenish-white, borne in axillary or terminal racemes
• Approximately 5–8 mm in diameter
• Blooming can occur year-round in tropical climates with peak flowering in spring and summer
Fruit:
• A fleshy drupe, ovoid to globose, approximately 2–4 cm long
• Skin color varies by cultivar: white, pink, red, or deep purple when ripe
• Thin skin surrounding a single large seed (endocarp is hard and woody)
• Pulp is white to pale yellow, with a mild, slightly sweet to bland flavor
• The seed kernel is edible and has a flavor reminiscent of almonds
Habitat:
• Coastal dunes, sandy shores, and beach margins
• Edges of mangrove swamps and coastal hammocks
• Tolerates saline soils, salt spray, and periodic saltwater inundation
• Found from sea level to low elevations
Ecological Role:
• Provides food and shelter for coastal wildlife, including birds and small mammals
• Fruit is consumed by numerous bird species, which aid in seed dispersal
• Dense growth habit makes it valuable for coastal erosion control and dune stabilization
• Tolerates poor, sandy, and alkaline soils where many other species cannot establish
Reproduction:
• Pollinated by insects, particularly bees
• Seeds dispersed by birds, mammals, and ocean currents (the buoyant fruit can float and remain viable in saltwater for extended periods)
• Can also propagate vegetatively through root suckers
Light:
• Prefers full sun to partial shade
• Performs best with at least 6 hours of direct sunlight daily
Soil:
• Highly adaptable; tolerates sandy, loamy, and clay soils
• Tolerates saline and alkaline conditions (pH 5.0–8.5)
• Requires well-drained soil
Watering:
• Drought-tolerant once established
• Regular watering recommended during the first growing season to establish root system
• Avoid prolonged waterlogging
Temperature:
• Thrives in USDA hardiness zones 10–11
• Can tolerate brief exposure to temperatures near 0°C but sustained cold causes damage
• Optimal growth in warm tropical to subtropical climates
Propagation:
• By seed: collect ripe fruit, clean pulp, and sow seeds fresh (viability declines with storage)
• By cuttings: semi-hardwood cuttings root readily in moist, well-drained medium
• By root suckers: naturally produces suckers that can be separated and transplanted
Pruning:
• Responds well to pruning and can be shaped into hedges or topiary
• Tolerates shearing, making it an excellent choice for formal or informal hedging
Fun Fact
The Coco Plum's fruit is remarkably buoyant and salt-resistant, allowing it to float in ocean water for weeks while remaining viable. This adaptation has enabled the species to colonize coastlines across vast oceanic distances — from the Americas to western Africa — making it one of the relatively few plant species with a natural transatlantic distribution. • The seed's hard endocarp protects it from saltwater damage during oceanic dispersal • This dispersal mechanism is shared by only a handful of coastal tropical species • The plant's ability to thrive in saline, sandy, and nutrient-poor soils has made it a valuable species for coastal restoration and dune stabilization projects worldwide • In the Caribbean, the fruit is traditionally used to make a sweet preserve, and the seed kernel is sometimes roasted and eaten for its almond-like flavor
