I thought, this was a Camassia plant in my garden but obviously not! (As I have them planted near this one) It looks like a grass or something and has this flower head already... any idea what this is???
Looks like Carex pendula to me. I grew it as an interesting grass in Essex. Gave some to a friend in Devon and it took over their garden. His wife is still not talking to me. In Devon it can be an invasive weed, due to the higher rainfall. Dig out rather than pull out as it will shred your hands quite happily.
To be quite honest , I've never even heard of 'Yorkshire Fog' as relating to a plant ; shows that only botanical names will do .
If it is Carex pendula , it can be a real pain in the ar*e as it seems to seed around everywhere .
