- Prefers to grow in open grassy areas such as fields, meadows, pastures, forest clearings, and roadsides.

What you can do about it:
- If you think you’ve found mouse-ear hawkweed anywhere in Oregon, please report it to the Oregon Invasive Species Hotline.
- Do not mow mouse-ear hawkweed flowers, this only stimulates the plant to re-grow.
- If there are only a few plants, hand digging is an effective option, but the entire plant must be removed. Once removed, throw away the plant parts in a plastic bag in the trash— not your yard waste bin or home compost.
Dandelions (Taraxacum officinale) produce similar looking flowers to mouse-ear hawkweed. Dandelions leaves are more deeply cut and do not have fuzzy leaves that are symbolic of mouse-ear hawkweed.
