Pheasant's eye  (Adonis annua)

This winter annual germinates towards the end of autumn and flowers in June and July (2). Very few seeds are produced by each plant, and their large size and heaviness restricts the colonisation of new areas. It is likely that the seeds are able to lie dormant for many years in the soil until conditions become suitable again, as the plant has re-appeared after clearings are created in woodlands (2).
