Common Questions
Leadwort questions
What zones can Leadwort grow in?
Leadwort is hardy in USDA Zones 5–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Leadwort deer resistant?
Yes — Leadwort is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does Leadwort bloom?
Leadwort typically blooms in late summer through early fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Leadwort need full sun?
Leadwort does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Leadwort drought tolerant?
Yes — once established (usually after the first full season), Leadwort handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
