I was thinking about the flowers. Hibiscus flower tea is popular around here.
I know they call it "Hibiscus Petal" tea, but they are actually the CALYCES of H. sabdariffa. That's one species I can't grow (unless maybe briefly in the summer). Too tropical.
(to me, it tastes too much like "kool-aide" (tm).)
H. acetosella does have petals that are used RAW to make smoothies.
If you ever have time and budget to come out here, you can see all my other Hibiscuses. Some of them have flowers roughly 16 inches across. That one's a bit over-the-top actually; I have more tasteful varieties too.
I have Abutilons too. Same family--Malvaceae--but from South America. You might have heard of them as "Flowering Maples". On the East Coast they are houseplants but some of them are outdoor shrubs here, that are among the few in the family that grow in shade.
Oh, one flower I know you of all people would love--Lord Anson's Pea, Lathyrus nervosus. A South American "sweet pea" that is both fragrant AND perennial (the Common Sweet Pea, L. odoratus, is alas annual).
