Checker Mallow questions
What zones can Checker Mallow grow in?
Checker Mallow 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 Checker Mallow deer resistant?
Yes — Checker Mallow is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does Checker Mallow bloom?
Checker Mallow typically blooms in early to 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 Checker Mallow need full sun?
Checker Mallow does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Checker Mallow drought tolerant?
