Onionweed

Asphodelus fistulosis

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.
