Common Questions

Silver Geranium questions

What zones can Silver Geranium grow in?

Silver Geranium 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 Silver Geranium deer resistant?

Yes — Silver Geranium is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.

When does Silver Geranium bloom?

Silver Geranium typically blooms in early summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Silver Geranium need full sun?

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

Is Silver Geranium drought tolerant?

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