Common Questions
Green Amaranth questions
What zones can Green Amaranth grow in?
Green Amaranth is hardy in USDA Zones 7–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Green Amaranth deer resistant?
Not reliably. Deer may browse Green Amaranth, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Green Amaranth bloom?
Green Amaranth typically blooms in mid-summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Green Amaranth need full sun?
Green Amaranth does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Green Amaranth drought tolerant?
Yes — once established (usually after the first full season), Green Amaranth handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
