• Latin name: Averrhoa carambola
• Danish names: Star fruit, carambola
  
• English names: Carambola, star fruit and five-corner
  

Averrhoa carambola is a tropical to subtropical fruit tree, known worldwide for its characteristic star-shaped fruits, which appear when the fruit is sliced crosswise. The species originates from Southeast Asia, but is today cultivated in large parts of the tropical world for both its decorative and culinary qualities.

The plant develops into a small to medium-sized tree with slightly drooping branches and fine, pinnate foliage, which provides an elegant and light appearance. During the flowering period, small, pink to lavender-colored flowers form in dense clusters directly on the branches and trunk. After pollination, the well-known fruits develop, ripening from green to yellow and having a crisp, juicy texture.

The flavor varies depending on variety and ripeness and ranges from freshly tart to sweeter, often with notes of citrus and apple.

Cultivation and requirements

Averrhoa carambola thrives best in very bright to full sun and prefers:

• nutrient-rich, well-drained and slightly acidic soil
• even watering during the growing season
• warmth and shelter

The plant is not frost-tolerant. In Denmark, star fruit is grown as a potted plant, which can be outdoors in the summer months and overwintered in a bright, frost-free location. The temperature should preferably be kept above 12–15 °C, and preferably warmer for optimal growth. During cooler periods, the plant may lose some foliage, which is normal.

Cultivation from seed

Star fruit grows well from seed, but it is important to be aware that seed-grown plants can vary in both growth and fruit quality.

For best results, it is recommended to:

• sow fresh seeds, as germination capacity drops quickly
• sow in an airy, well-drained soil mix
• temperature of 22–28 °C
• keep the soil evenly moist, but not wet

Germination typically occurs within 1–3 weeks, but it can take even longer. Young plants grow relatively quickly under good conditions, but it may take several years before a seedling potentially reaches flowering and fruit-bearing age.

Utility and collector value

Averrhoa carambola is grown as both a fruit and ornamental plant. The fruits are used fresh, in salads, desserts, juices, and as decorative garnishes where the characteristic star shape comes into its own.

As a plant, star fruit has great collector value, especially for those who wish to grow exotic fruit trees from seed. The combination of beautiful foliage, decorative flowers, and unique fruits makes it an exciting long-term project.

Averrhoa carambola is an obvious choice for the patient plant enthusiast who wants to grow an iconic tropical fruit tree entirely from seed – with both aesthetic value and the potential for harvest under the right conditions. 🌿⭐
