Erigeron annuus (weed) (L.) Pers. - (annual fleabane)

This plant is native to North America and has been introduced as an ornamental into Europe, parts of Asia and Australia. It can become common and invasive in some habitats which are semi-open and open, including grasslands, farms and forest edges. Fields with cereals are frequently invaded and invasion is facilitated by the rapid growth of the weed and its high seed production.
