Common Questions
Siberian Catmint questions
What zones can Siberian Catmint grow in?
Siberian Catmint is hardy in USDA Zones 4–8. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Siberian Catmint deer resistant?
Yes — Siberian Catmint is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.
When does Siberian Catmint bloom?
Siberian Catmint typically blooms in early summer through early summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Siberian Catmint need full sun?
Siberian Catmint does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Siberian Catmint drought tolerant?
Yes — once established (usually after the first full season), Siberian Catmint handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
