I inherited a garden full of columbines / akeleier (Aquilegia vulgaris) and there’s a range of different forms. I took the pictures below yesterday. I tried sucking a couple of flowers for nectar but I guess the bees got there first. I had found a paper documenting that children sucked / ate the flowers for the nectar: “People considered it more a children amusement than a feeding behaviour.” They are not so poisonous that it’s necessary to remove the flowers if children are around which is a custom here in Norway.
Ref. Wild edible plants traditionally gathered in Gorbeialdea (Biscay, Basque Country).
Otherwise this is a plant that has escaped from gardens throughout the country! I’ll leave them to the bees!
