Identifying succulent plant from Snowdonia
I'm stuck for an ID on a plant growing along the Devil's Kitchen path on the northern edge of Snowdonia national park in Wales.
It is an erect succulent with yellow flowers that was perched on a large boulder. I couldn't get close enough to have a good look at the flowers. The photo isn't incredibly detailed but gives a general idea of floral structure if you zoom in.
Many thanks in advance for your help.
