Anthriscus sylvestris.

I know, it's that bloomin' cow parsley again. I'm unnaturally drawn to it. I think because it's so satisfying to photograph and I love the star burst effect of the clusters. Sorry, but this will probably not be the last you'll see of my abundant little friend!

'Cow parsley is one of the most familiar wild plants of the British countryside. Throughout the month of May, most roadsides are lined with the white flowers, seemingly impervious to traffic pollution, salt-spray and regular mowing by the highway authorities. The plant has a number of local names; hedge parsley, wild chervil and Queen Anne's lace. The latter apparently arose from the days when Queen Anne travelled in May and people believed the roadsides had been decorated especially for her. Cow parsley belongs to the family of umbellifers, plants that bear their flowers in umbrella-like clusters. The flowers are small and white, and the plant's leaves are feathery and fern like.'
