With pictures is better😀

Some people make a very delicious herbal tea with hibiscus - however, I do not know the botanical name of the particular plant used. Perhaps someone here will know. The tea tastes good without any sweetener.

Hibiscus tea is made from Hibiscus sabdariffa, not H rosa sinensis. And the flowers are picked fresh, not after they have wilted and died. Imo the best use for the latter is as an addition to the compost heap, although they are apparently edible when fresh and can be used as a dye plant. Hibiscus Dye - Rosa Sinensis — All Natural Dyeing

Hurray, I thought someone would know the right plant!! This is making me thirsty.
