Chamerion angustifolium
(Map updated: March 2008)
 

Very common on cleared ground in forestry plantations, on waste ground etc. Also a rare species of cliff ledges high up in mountains such as Eagle Mountain in the Mournes. The mountain sites may be its original wild habitat from which it has spread to lowland man-made habitats in recent times.

All names: Chamerion angustifolium (L.) Holub; Epilobium angustifolium L.; Chamaenerion angustifolium (L.) Scop.; Chamaerion angustifolium (L.)
