Nice pics pleb. I've learnt something today. I often see those blue flowers but never knew they were called Green Alkanet. You'd think they would be called Blue Alkanet, but I suppose most of the colour is in the leaves.
To the best of my knowledge green alkanet is not a native wild flower, it is one that has escaped from cultivation (as a herbal plant) and has become a naturalised part of the landscape. Its bristly leaves can irritate the skin, particularly children's.
It's surprising that Greater Celandines look nothing like Lesser Celandines. I think they are two entirely different species.
Correct, greater celandine is a member of the poppy family while the lesser one is a member of the buttercup family. That's the problem with common names, they can be quite misleading. Only the scientific names as used by botanists make the real differences clear (which is why there are scientific names, they mean anyone in the world, whatever their language, can refer to the same species).
