Red Skin Yacon is a named or marketed type of Yacon distinguished by the reddish appearance of its underground storage roots. Yacon varieties can differ in root skin color, flesh color, size and growing characteristics. The exact characteristics of Red Skin Yacon depend on the genetic identity of the planting material supplied.
Yacon can grow from true seeds, but seed propagation is relatively uncommon because seed production and germination can be inconsistent. Seed-grown plants may also show variation in their characteristics. Rhizome crown divisions are generally preferred because they provide a more dependable way to establish plants with characteristics similar to the parent plant.
Yacon generally requires a long growing season to develop mature underground storage roots. The time to harvest varies with climate, planting material, soil fertility and growing conditions. Plants established from true seeds may take longer or develop differently from plants grown from rhizome divisions. Harvest when the crop has matured and above-ground growth begins to decline.
