This Spurge was found in dense vegetation in a remote valley in S Wales.
No interactions present.
Not sure about the 'Fireglow' but yes to Euphorbia griffithii. I think ours is 'Dixter' and is a bit redder than this one.
This was actually taken by Richard Pryce with my camera as he had crossed the intervening barbed-wire fence. I agree to drop the Fireglow.
