Identify Please

I am trying to Identify a Shrub growing in my Garden in Essex, UK. The Shrub is Evergreen, and fully Hardy, it is about 2.5 Metres High, and 2 metres across, it is in Bloom in June and July, and bears a large number of Flowers. The Flowers resemble those on the ground covering "Hypericum".
I attach a Photo of a Bloom, and will appreciate any Help

 

It resembles Hypericum, as it is one! They come as tall and small shrubs.
A common one in the UK Is Hypericum Hidcote, it grows 2m x 2.5m spread.

Sorry I cannot tell you exactly which one you have.

 

Another common one looking like this is Rose-of-Sharon Hypericum calycinum.

 

That last produces larger anthers relative to the diameter of the flower.

 

Thank you all for your help, very quick and much appreciated, Bombom

 

Looks like St. John's Wort. I have a huge bed of it in my yard. Great groundcover!
