Elegant husks--yarrow calyxes in Fairbanks Alaska

I was out taking photographs and came across this lovely stalk of common yarrow (Achillea millefolium).  What you are looking at are the calyxes (plural of calyx), left after the seeds have dispersed. These are the outer protective layer of the flower. The corolla is the inner leafy part of the flower, and what would be called the petals of a flower are called the sepals of the calyx.
