- It can become unmanageable on open range lands or pastures.
- Has yet to be observed in BC but is present in the state of Washington.
- They displace native plant species.
- Reduce wildlife foraging and habitat.
- Under the right conditions will escape cultivation and take over exposed sites.
Prevention is a high priority for this species.
- Maintain good ground cover to slow the spread and prevent invasive establishment.
- Do not purchase, plant or distribute clary sage.
- Learn to identify clary sage.
- Report this plant if you think you have seen it.
