About Air potato
Dioscorea bulbifera, also known as air potato or air yam, is a vigorous tropical vine renowned for its edible aerial tubers (bulbils) that develop in the leaf axils. Its large, heart-shaped leaves provide lush foliage, making it ideal for covering pergolas, fences, or structures in tropical and subtropical gardens, or as an ornamental plant in large pots where its stems can trail. It's a fascinating plant due to its rapid growth and the curious formation of its bulbils.
Native range
Tropical Africa and Asia
Care tips
This plant prefers full to partial sunlight and well-drained soil rich in organic matter. Keep the substrate consistently moist, especially during the growing season, but avoid waterlogging, which can lead to tuber rot. A common mistake is underestimating its vigor and failing to provide adequate support for climbing, which can result in sprawling growth. In temperate climates, bulbils can be harvested before frost and replanted in spring.
