It’s everywhere at the moment, lining shady stretches of country lanes and stretches of woodland. It has lots of alternative names including fairy lace. Some think it looks like drifts of snow. It is of course, a popular plant with pollinators.
Cow parsley is a member of the carrot family. It can be confused with hemlock and hogweed, one of which is poisonous and the other which has sap that can burn the skin.

It looks a little like Queen Anne’s Lace that flowers in the fall where I live. Awesome picture!

Thank you. Yes it is. It appears here in late Spring/early Summer then starts to die back. To me it’s strange that it flowers in fall in America!
