Habitat & Ecology
- Commonly overtaking disturbed sites, fields, rangelands and more recently agronomic crop sites.
- Has yet to be observed in Canada.
- This plant is unpalatable to livestock and reduces foraging opportunities for livestock.
- Contaminates alfalfa seed crops.
- Reduces native plant biodiversity.
Prevention is a high priority for this species.
- Maintain good ground cover to slow the spread and prevent invasive establishment.
- Learn to identify Mediterranean sage.
- Report this plant if you think you have seen it.
