Akee (Blighia sapida)
Discover the Akee, Blighia sapida, an evergreen tree native to West Africa, famous for its unique edible fruit and shade structure.
Complete Plant Information
Overview
The Blighia sapida, commonly known as Akee, is a striking broadleaf evergreen tree renowned worldwide, especially as the national fruit of Jamaica. This species, thriving in tropical and subtropical environments, offers structure and seasonal visual interest with its greenish white, fragrant blooms followed by distinctive, brightly colored fruit capsules. Gardeners seeking a significant tropical specimen will find the Akee a rewarding, albeit sometimes high-maintenance, addition to the landscape.
Growing reliably between 25 and 50 feet tall with a similar spread, mature Blighia sapida provides substantial shade. While its appeal is undeniable, recognizing its tropical needs—specifically its requirement for warmth—is crucial for success outside its native Western Africa range. Its unique reproductive cycle and the culturally significant fleshy arils demand specific handling.
This evergreen tree provides year-round foliage, eventually developing smooth gray bark as it matures. The combination of showy flowers and the fascinating opening process of its toxic-when-immature fruit makes Blighia sapida a plant of considerable botanical interest, perfect for large tropical yards or botanical collections.

How to Grow
Planting the Akee should occur during the warmest time of the year, allowing the tree to establish a strong root system before potentially cooler periods. Blighia sapida thrives best where it receives full sun daily. In terms of soil, it adapts well to various conditions; however, optimal growth is seen in moist, fertile, loamy, and well-drained soils, though it tolerates less fertile sandy soils successfully.
Watering requirements are medium; consistent moisture is important, especially for young trees, but standing water must be avoided to prevent root issues. Fertilization should be approached seasonally, favoring a balanced feed to support vigorous growth characteristic of tropical evergreens. Pruning is generally minimal, focusing mainly on removing crossing branches or shaping the structure when the tree is young.
For gardeners in marginal zones, protection from cold is non-negotiable, as this species is only winter hardy to USDA Zones 10-12. If temperatures dip near freezing, coverage or temporary indoor relocation (if containerized) is necessary. During active growth periods in the warmer months, ensure irrigation matches the medium water need to support leaf canopy development.
Landscape Uses
The Akee functions excellently as an interesting small tropical tree within the landscape design, despite its potential mature size, offering a strong vertical element. Due to its significant mature height and spread of up to 50 feet, it works best when sited away from structures, making it ideal for providing centralized shade in expansive yards or park settings.
When using Blighia sapida, consider mass plantings where its robust canopy can create an immersive tropical feel. While its flowers are showy and fragrant, the primary visual draw for many is the fruit and foliage structure. Companion planting should focus on other moisture-loving, sun-tolerant tropical plants that can benefit from the filtered light the Akee provides as it matures.

Noteworthy Characteristics
Blighia sapida, commonly known as ackee or akee, is an evergreen tree of the soapberry family that typically grows to 25-50’ tall. It is native to tropical West Africa and was introduced to Jamaica in the mid-1700s. Mature trees feature smooth gray bark and pinnate leaves; small, fragrant, greenish-white flowers appear seasonally. The pear-shaped fruit opens to reveal seeds partially covered by edible white fleshy arils, toxic if the fruit is unripe or overly ripe.
Tolerances
- Rabbit
- Deer
Potential Problems
The Akee tree generally exhibits strong resistance, reporting no serious insect or disease problems under ideal growing conditions. This resilience is a major benefit for tropical gardeners seeking low-fuss specimens. If pests like scale or mealybugs become an issue during periods of stress or excessive humidity, treatment with horticultural oil is usually sufficient. Ensuring excellent drainage is the best management practice to prevent root-related issues associated with its medium water needs.

Conclusion
The Akee (Blighia sapida) offers a unique blend of tropical aesthetic appeal, fragrant seasonal flowers, and significant cultural relevance through its distinctive fruit. While requiring consistent warmth typical of Zones 10-12, its general resilience to pests makes it a worthwhile choice. Plan your planting location carefully to accommodate its substantial size and ensure optimal growing conditions to enjoy this fascinating evergreen.
Design Ideas for Tropical Canopies
When integrating the Blighia sapida into a landscape, treat it as a primary specimen tree due to its stature. Its rounded canopy provides excellent, albeit dappled, shade, making it a good anchor point for ground-level plantings that prefer partial shade once the Akee matures. Group it with other fast-growing tropical hardwoods to establish a lush, layered canopy effect quickly in suitable zones.
Consider the mature spread (up to 50 feet) when placing it near property lines or walkways. The smooth gray bark adds textural contrast against rougher tropical foliage, offering visual interest even during the off-season for fruit production, reinforcing its value as a year-round evergreen feature.
Companion Planting Considerations
Because the Akee demands full sun and medium water, select companion plants that share similar cultural requirements. In the understory, look toward heat-loving foliage plants like Elephant Ears (Colocasia) or Bromeliads, provided they receive sufficient light penetration through the canopy. For tropical borders, consider flowering shrubs that handle bright light, such as Hibiscus or Ixora, allowing their vibrant colors to contrast with the tree’s greenish white blooms.
