Facts
Corn poppy is native to the eastern Mediterranean region and introduced in North America as well as Europe, where it is thought to have been imported as a "weed seed" with corn. In New England, It is found in abandoned homesteads, fields, forest clearings and dumps. Its bright red flowers are distinctive, and in Great Britain symbolize fertility as well as death. The very long-lived seeds, which can sprout after 80 years of dormancy, are regarded as symbols of remembrance.
Habitat
Anthropogenic (man-made or disturbed habitats), forest edges, meadows and fields
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.
