Common Questions
Johnson's Amaryllis questions
What zones can Johnson's Amaryllis grow in?
Johnson's Amaryllis 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 Johnson's Amaryllis deer resistant?
Not reliably. Deer may browse Johnson's Amaryllis, especially tender spring growth — plan on repellents or fencing where pressure is high.

Johnson's Amaryllis typically blooms in spring through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Johnson's Amaryllis need full sun?
Johnson's Amaryllis does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Johnson's Amaryllis drought tolerant?
Yes — once established (usually after the first full season), Johnson's Amaryllis handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
