Briony is right , the plant in my garden that I could not identify is indeed wood spurge . Thank you clever lady .
I shall have to continue to pull it out . Apparantly it spreads by rizomes .and will take over . It looks pretty but no thank you.I bought this desk last weekend so I could sit in the conservatory and machine , It's very stable , no shaking on the machine . It is made of oak .It has a little brass label on one of the drawers that reads Ministry of Defence .
I also bought a new garden seat . The old one was very dodgy , I was concerned someone would end up sitting on the floor.
