Botanical Description

Sacha Inchi is a perennial climbing vine that belongs to the Euphorbiaceae family. It is native to the rainforests of the Amazon Basin in South America but has been cultivated in other tropical regions as well. Sacha Inchi is a vigorous, twining vine that can grow up to 3-4 meters (10-13 feet) in length.

The plant has large, heart-shaped or ovate leaves that are dark green in color. These leaves can grow up to 15 cm (6 inches) in length. The leaf surface is smooth, and the plant is deciduous, shedding its leaves in response to seasonal changes.

Sacha Inchi produces small, inconspicuous flowers that are greenish-white in color. The flowers are unisexual, meaning the male and female flowers grow on separate plants. Pollination is primarily carried out by insects such as bees.

The plant's most distinctive feature is its fruit, which is star-shaped, with 5 lobes, and contains 4-7 seeds. The fruits are green when immature, turning yellow or brown as they ripen. The fruit has a leathery, somewhat woody shell, which protects the seeds inside.

The seeds of Sacha Inchi are edible and are the most important part of the plant in terms of nutritional and commercial value. The seeds are flat, oval, and have a rough, dark brown exterior. They are rich in omega-3 fatty acids, protein, and antioxidants, making them highly valued for their health benefits.

The plant's root system is fibrous and shallow, helping anchor the vine to the soil while also providing stability to the plant as it climbs.

Growing Instructions

Sunlight: Sacha Inchi thrives in full sunlight, requiring at least 6 to 8 hours of direct sunlight per day. It is essential to place the plant in an area with plenty of sun exposure for optimal growth and seed production.

Soil: The plant prefers well-drained, fertile soil with a slightly acidic to neutral pH (5.5–7.5). Sacha Inchi is particularly suited to soils that are rich in organic matter. To ensure the plant grows well, it is beneficial to enrich the soil with compost or organic matter before planting.

Temperature: Sacha Inchi thrives in tropical climates and requires warm temperatures to grow well. The ideal temperature range is between 25°C and 30°C (77°F to 86°F). It can tolerate slight variations, but it is important to protect the plant from cold temperatures, as frost can damage or kill the plant.

Watering: The plant requires moderate watering. Consistent moisture is important for healthy growth, but over-watering should be avoided, as this can lead to root rot. During the growing season, water the plant regularly, ensuring the soil is moist but not soggy. During the dry season, Sacha Inchi may require more frequent watering.

Spacing: When planting Sacha Inchi, it is recommended to space the plants about 1 to 1.5 meters (3 to 5 feet) apart. This spacing allows the vines to spread out and ensures they have adequate room to grow without overcrowding.

Pruning: Pruning is necessary to maintain the health of the plant and encourage higher yields. Prune the vines periodically to remove dead or damaged growth, and trim the plant to shape it as needed. Pruning also encourages better airflow, reducing the risk of fungal diseases.

Support: Sacha Inchi is a climbing plant that requires support as it grows. You can provide support with trellises, stakes, or other vertical structures. As the vines grow, they will naturally climb and attach themselves to the support, allowing the plant to thrive.

Life Cycle: Sacha Inchi is typically grown as a perennial but is often treated as an annual in regions outside of its native habitat. The plant has a relatively long life cycle, with several stages of growth.

• Germination: The germination process begins when the seeds are planted in warm, moist soil. Sacha Inchi seeds generally take 2 to 3 weeks to germinate under optimal conditions.

• Vegetative Growth: After germination, the plant enters a vegetative growth stage, where it focuses on producing leaves and roots. During this stage, it is important to provide the plant with adequate sunlight, water, and nutrients.

• Flowering: Sacha Inchi produces small white flowers that appear after a few months of vegetative growth. The flowering stage is crucial for pollination and fruit production. Flowers are typically pollinated by insects, although some may self-pollinate.

• Fruit Set: After successful pollination, the plant begins to form star-shaped pods containing seeds. These pods take several months to mature, and they are harvested when they turn brown and dry.

• End of Season: At the end of the growing season, the plant’s production slows down. In tropical climates, Sacha Inchi can be harvested year-round, but in other regions, it may be grown as an annual crop.

Harvesting and Foraging
