Common Questions
Yacon questions
What zones can Yacon grow in?
Yacon is hardy in USDA Zones 9–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Yacon deer resistant?
Not reliably. Deer may browse Yacon, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Yacon bloom?
Yacon typically blooms in late summer to fall through early fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Yacon need full sun?
Yacon does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
