Chrysobalanus icaco: complete guide

Overview

Chryssobalanus icaco, commonly known as coco plum or icaco, is a tropical fruit tree originating from southeastern America and West Africa. This medium-sized tree produces delicious, nutty fruits that have been appreciated by indigenous populations for centuries. The tree is also cultivated for its ornamental value.

In Europe, Chrysobalanus icaco can only be grown in very warm gardens or conservatories. The tree performs well in pots. With proper care, this tree will provide years of exotic fruit.

Appearance and bloom

Chryssobalanus icaco grows to a height of 2-5 metres with a compact, rounded crown. The leaves are small, leathery, and dark green in colour. They grow alternately on the branches. The leaves have a fine structure and are highly decorative.

The flowers are small, white or cream, and grow in umbel-like clusters. They appear mainly in early spring. The flowers have a pleasant aroma. After flowering, small, oval fruits form that turn white, yellow, red or dark purple at maturity. The fruits are approximately 2-3 cm long.

Ideal location

Chryssobalanus icaco grows best in full sun to partial shade. Ensure the tree receives at least 4-6 hours of direct sunlight daily. In very warm climates, some afternoon shade can be useful.

The tree grows better in warmth and humidity. In temperate climates, this tree must be kept in a warm greenhouse or conservatory. Ensure temperatures never drop below 10 degrees Celsius.

Soil

Chryssobalanus icaco grows in well-drained, nutrient-rich soil. A mixture of garden soil, compost and coconut coir works well. The pH should be between 5.5 and 7.0. Ensure the soil is moisture-retentive but not waterlogged.

Watering

Chryssobalanus icaco is quite a water lover during the growing season. Ensure the soil remains moist, especially during summer. Water regularly. In winter you can reduce watering. Ensure moisture levels remain consistently high.

Pruning

Chryssobalanus icaco requires minimal pruning. Remove dead or damaged branches whenever you notice them. You can slightly control the tree's shape by light pruning in early spring. Harvesting ripe fruits encourages more flowering.
