Identify a plant
Can anyone help me identify this plant please.
It is in a friends garden but they don’t know what it is but I would really like to get one.
Sheffield, Derbyshire border.
It's a Euphorbia, not sure which one.
He calls her the chocolate girl
Cause he thinks she melts when he touches her
She knows she's the chocolate girl
Cause she's broken up and swallowed
And wrapped in bits of silver
I’ve cheated and googled, could it be this one.
Euphorbia characias 'Glacier Blue'
Gardening on the wild, windy west side of Dartmoor.
