Fernbush 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 Fernbush deer resistant?

Does Fernbush need full sun?

Is Fernbush drought tolerant?
Yes — once established (usually after the first full season), Fernbush handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
