I purchased some plants from an open type market . This plant was growing on Anna Maria Island, in FL. There were two very tall, scraggly plants in a pot. I tried to grow them in the pot but they seemed to need more room so I put them in full sun in the ground. I was very surprised to see they grew so tall and fast. They dropped seeds and regrew in several other potted plants, but not very well. They seem to prefer the ground and not a pot. The blooms are smallish but very pretty. I have been using them to shade my deck and windows since they grow taller than my roof. After the seed pods form and dry, the plants are easily pulled out when they start to look bad. Since they grow so tall I have had to tie them up to keep them from drooping on the ground.
I wanted to use the blooms as tea but was afraid to try it until I see here that they are useable for tea.
The kind you want for making tea is the Roselle, Jamaican Sorrel or Florida Cranberry hibiscus. You use the calyxes for tea (not the leaves that I know of): http://davesgarden.com/guides/pf/go/2113/
