I found these winter aconites Eranthis hyemalis just coming into bloom near Wolsingham in Weardale yesterday, amongst trees beside a stream. I've known them from this spot for 35 years and they must have been planted there long before that. I've tried to establish them in my own garden on a few ocasions with no success - maybe they need a little more neglect and some sheep hooves to churn up the soil in winter...
They come from southern Europe but are well naturalised in quite a few places around here. I've seen them in hedgerows in the Tyne valley, near Corbridge.
These early flowers are a little weather-beaten. They are unusual because the structures that look like yellow petals are really coloured sepals and the real petals are reduced to small, rolled-up green tubes that fill with nectar, located within the flower below the stamens - you can see one clearly at the 5 o'clock position in this photo. Hellebores, which are fellow members of the buttercup family, have a similar floral arrangement. Both are early bloomers so I imagine that these 'vases' of nectar have evolved to lure the few pollinators that are around on early spring days, on the lookout for an energy top-up....
