Cranberry Hisbiscus Starters

There are around 300 species of hibiscus plants, but cranberry hibiscus is one of the showiest with vibrant pink and red flowers and palmate leaves in a dramatically dark burgundy hue.  And the leaves are edible!  It is similar to but is not Hibiscus Roselle.  It can grow up to 8 feet tall and 3 feet wide.  Hardy zones 8 to 11.
