I have a green plant taking over my lawn and borders. I think it may be resulting from bird seed feed
Thanks for contacting us, but we are not able to help you with your plant ID.
Here at the Pennsylvania Horticultural Society (PHS), we work with gardeners interested in mid-Atlantic east coast plants. We do not have resources to ID plants from the UK.
For UK residents, we suggest you contact the Royal Horticultural Society.
If they cannot help you, they will direct you to an alternative local source.
