Here is an illustration of Thai Red Roselle from earlier this year:
Its "bright red calyxes make a "zingy" tea, sauce, or jam.
The tea is widely popular in Egypt where it's called karkade. Roselle
was called "Florida cranberry" in the 1890s and is still sometimes
called sorrel or Jamaica sorrel. The creamy-white flowers and young
leaves are edible and have a citrus tang. It is also grown in warmer
areas as a thick ornamental annual hedge."
And if anyone who is reading is near Nashville, TN I have some prints up in the O Gallery in the Arcade this weekend for the gallery crawl.
