Common Questions
Beargrass questions
What zones can Beargrass grow in?
Beargrass 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 Beargrass deer resistant?
Not reliably. Deer may browse Beargrass, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Beargrass bloom?
Beargrass typically blooms in late spring to summer through late fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Beargrass need full sun?
Beargrass does best in full sun (6+ hours).
Is Beargrass drought tolerant?
Yes — once established (usually after the first full season), Beargrass handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
