Can anyone help with this flower?

[GrandmaSue]

Photographed this last year in a hedgerow. It looks like cow parsley but is only about 12-14 inches high and is very delicate. The second photo is of the leaf it is the one in the middle with a pinkish tinge.

Maybe rough chervil, Chaerophyllum temulentum.

[Hedera]

I agree - rough hairy purply stems and delicate flowers.

Rough Chervil is the only umbelifer, apart from the much taller Hemlock, that has purple-spotted stems. The whole plant usually turns purple later in the year, becoming very distinct.
Not quite as common as Cow Parsley and Hedge Parsley.
