Origin: Asia and the Mediterranean Impact: Similar in appearance
to wild onion but lacking the onion scent and taste. Found in
pastures and rangeland, onionweed develops populations that
exclude grasses and desirable forage species. This federally
regulated weed poses a serious environmental and agricultural
threat. It seeds prolifically and can establish large
populations quickly. Learn More: Species Profile. If you have
