Solanum etuberosum, commonly referred to as the Chilean potato vine, is a perennial herb native to the central Chilean Andes, where it thrives in sunny, open areas with well-drained soils. It is a wild relative of the cultivated potato and is adapted to high altitudes and cool climates. This species typically grows to a height of 1-2 feet (0.3-0.6 meters) and spreads to a similar width. Solanum etuberosum is characterized by its sprawling habit and large, showy purple flowers that bloom in the summer months, adding ornamental value to gardens.

The Chilean potato vine is valued for its potential in breeding programs due to its resistance to various potato viruses, aphids, and frost, which can be important traits for improving cultivated potato varieties. While it does not produce significant tubers for consumption, its attractive flowers make it a candidate for ornamental use in gardens, particularly in rockeries or as part of a mixed border. It prefers full sun to part shade and requires well-drained soil. Although not widely cultivated, it can be grown in regions with a similar climate to its native habitat. Gardeners should be aware that, like many Solanum species, it may be susceptible to late blight and other fungal diseases.CC BY-SA 4.0
