Hardy hibiscus is the showiest flower in the garden. It blooms from late summer to fall. I have over a dozen named varieties in shades of red, pink and white, but only a few of them set seed. About half of the seeds in this mix came from the hibiscus in this picture, Luna Pink Swirl. Some of the seeds came from solid red, pink or white varieties. Of course, they don't come 100% true to type, so you should end up with an interesting mix of colors.
Did you know that hibiscus flowers are edible? They taste like a tangy lettuce. Also known as Dinner Plate Hibiscus, Rose Mallow, and Swamp Mallow. Hardy in zones 5-11.
