Not sure what the flower is, it is at the top of very tall stems, well over six foot high, in fact I had to stand on a garden table to get this shot. The leaves coming off the stems are very fine, sort of fern like.
It came out of a packet of seeds of insect friendly flowers.
I am guessing the bee doesn't know what the flower is either ,but he appears to be enjoying it.
With thanks to Paula W @paulaw I now know the flower is a Cosmos
