It is a bud, but not quite a bud as we know a bud to be because it does not contain a flower, but seeds. A lot of seeds that are dispersed to various places in the garden when it springs open. It is an anemone seed pod, but I find it so delicate and wonderfully shaped, it deserves a place in single flowers or bud, after all it is a bud of some sort.
And I have sunflowers in my garden in Summer, usually a surprise from the fallen bird seeds.
