Common Questions

Red Amaranth questions

What zones can Red Amaranth grow in?

Red Amaranth is hardy in USDA Zone 10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Red Amaranth deer resistant?

Not reliably. Deer may browse Red Amaranth, especially tender spring growth — plan on repellents or fencing where pressure is high.

When does Red Amaranth bloom?

Red 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 Red Amaranth need full sun?

Red Amaranth does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Red Amaranth drought tolerant?

Yes — once established (usually after the first full season), Red Amaranth handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
