Ground Apple, also called Yacon or Peruvian Ground Apple, is a perennial plant scientifically known as Smallanthus sonchifolius. It produces large underground storage tubers with a crisp, juicy texture and mildly sweet flavor. The plant also develops broad green leaves and small yellow flowers.
Yacon is most commonly propagated using underground rhizomes or crown divisions containing healthy buds. These are planted in prepared, well-drained soil during the suitable growing season. Although true seeds may be possible, rhizome propagation is generally preferred for reliable plant establishment.
Ground Apple tubers are generally harvested toward the end of the growing season, often when the above-ground foliage begins to die back. Carefully dig around the plant to collect the mature storage tubers without damaging them. Harvest timing depends on local climate and plant development.
