This is Narcissus poeticus var. recurvus, a selection from the wild with a long history of cultivation. I don't usually write about daffodils this late in the season but this is a late flowering species.
 I tried them in the garden, too shady. So I planted a number on the allotment last autumn which suits them better. Not edible of course but the soul needs feeding too!
 I have seen photographs of thousands upon thousands of N. poeticus growing in alpine meadows on the continent. That really is poetry.
