Mouse-Ear Hawkweed gets its name from its small, hairy leaves that resemble the appearance of mouse ears. The leaves form low basal rosettes and have distinctive whitish, hairy undersides.
Mouse-Ear Hawkweed spreads through wind-dispersed seeds, above-ground runners called stolons, and underground rhizomes. These spreading structures allow it to form dense mats and compete with surrounding vegetation.
Yes. Mouse-Ear Hawkweed is considered invasive in parts of North America, including the USA. It can spread into grasslands, lawns, and natural habitats, displacing native plants. Check state and local invasive-plant regulations before purchasing, selling, or planting its seeds.
