Yacon is the sunflower relative that stashes inulin in crunchy tubers — sweet on the tongue, polite on the glycemic gossip if you believe the brochures. Top growth dies with frost; underground crowns come back where winters are mild. subtropical and tropical Americas: mulch crowns, hedge bets on freezes. ☀️💧 Sun and Water Requirements: - Full sun to light afternoon shade in brutal heat. - Steady moisture during tuber swell; drought makes woody, sullen roots. - Deep loose soil; compaction fights tuber expansion like bureaucracy. ✂️ Methods to Propagate: - Rhizome crowns: divide dormant storage organs before spring growth. - Stem cuttings: possible in warm humid conditions — slower than crown division.
