Common Questions

Hollyhock questions

What zones can Hollyhock grow in?

Hollyhock is hardy in USDA Zones 4–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Hollyhock deer resistant?

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

When does Hollyhock bloom?

Hollyhock 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 Hollyhock need full sun?

Hollyhock does best in full sun (6+ hours).

Is Hollyhock drought tolerant?

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