can anyone positively identify this for me.

After a long hard search I have finally found it.
It is Cinquefoil a herb.
Frey

Looks like ground elder to me, and it is a real pain - highly invasive and difficult to get rid of. The tiniest bit of root will grow back if you leave it in the ground.

As it's got 5 leaves, my vote goes to cinquefoil and yes it is a real thug, although prettier than ground elder but just as invasive - exterminate, exterminate!

Get rid of it know .I t is what aunt sally said chinkysomething a reall pain if you let it grow.
Having said that it could be a potentilla of some sort but this group contains some weeds too.If the leaves are quite hairy it could be'Monarchs Velvet' but I dought is so as the vicar said to the nun'if in dought pull it out'
