Yacon (Smallanthus sonchifolius) is a perennial root vegetable traditionally grown in warm regions with long growing seasons. These heirloom seeds develop into robust plants with large green leaves and well-formed underground tubers when provided with rich soil and steady moisture.

Seeds can be started early and transplanted once temperatures are consistently warm. Smallanthus sonchifolius grows best in sunny locations and loose, well-drained soil. Plants reach maturity toward the end of the season, offering a distinctive harvest that appeals to gardeners interested in growing uncommon vegetable varieties.
