Now I often walk around the garden to see what is changing. In amongst this plant I think it might be a sort of poppy growing up! Its very small.
Will see when it pops!
@sdutoit Thank you Sylvia - for your thoughtful comment! Last time the leg was looked at 2 days ago - there was still that horrible greeny black eschar on it. It is drying out gradually and may be removed bit by bit.
