Weed or Plant

Hi could anybody please identify this plant.

 

Difficult to identify at this angle, but could be something like hogweed, or cow parsley. Would need to see the leaves and the height really.

 

I would agree with Blackthorn, it does look like the cow parsley family from that angle. But each flower would need to be on a stalk coming from the same place - as in Umbellifer- see here http://www.dundeetwig.com/umbellifer.jpg

It looks refined so Ammi majus springs to mind. http://www.everwilde.com/store/media/2009-large-wildflower-photos/Ammi-majus.gif

So many garden plants are not far removed from wild flowers. If you like it it is a garden plant. If you don't its a wild flower, ie weed.
