This is broken part of Hibiscus flowers which is the sifting. This is second layer of the flower.
Hibiscus flowers only last for one day on the stem, but keep considerably longer when dried and stored properly.
The brightly colored blooms are typically dried for use in making teas and other beverages, including alcoholic cocktails. But don't overlook other culinary possibilities—sprinkle the dried flowers into soups and custards or mix into bread dough before baking.
You can also use bits of dried hibiscus flowers to decorate table settings, homemade cards, gift bags and more.
