Does anyone recognise this please?

When I worked in the garden centre, I was on the till one day and a guy walked in with this healthy looking plant in a 9cm pot. He looked so chuffed with his plant that I took his money. I didn`t have the heart to tell him that it was a stinging nettle.:D:D A true story.

 

I've got one of those and I don't think it's the same, but maybe there are different varieties. I'll have to wait and see if it flowers.

Thanks all for your help.
