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?
Not reliably. Deer may browse Hollyhock, especially tender spring growth — plan on repellents or fencing where pressure is high.
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 to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
