Thanks CozyHollowGirl, I just got a large-flowered red hibiscus for my birthday (upcoming) and have ordered seeds and a plant of different varieties. I found that the hibiscus I was buying is not the blossoms but the seed "pod" so I am glad to hear that the blossoms from ordinary hibiscus are fine. It has helped my b.p. as well. Does the flower-type you use have a tartness too? If you look up edible hibiscus even the leaves are edible and it said the roots are used to make meringue! Rita
