Ephemeral

Ollie dog and I had a slow walk at Parndon by the River Stort this afternoon.  Swarms of mayflies were dancing above this lovely lime-green spurge. I'm familiar with the little sun spurge and the large Mediterranean spurge but am not sure which this one is. It looks a bit like wood spurge but it is about three feet tall and the leaves are regularly placed up the stem. I'll have to do some more research. I do love Euphorbias though.
