Hibiscus are showy shrub like plants known for their large over the top flowers which can be over 1 foot wide. Their are two groups people often think of with Hibiscus that is tropical and hardy hibiscus. I mainly deal with hardy Hibiscus which can survive zones 4 to 9. The new breeding being done is changing all the rules we have known on this group. With new foliage colors as well as new flower colors. This group is getting a exciting upgrade compared to the plants your grandmother grew.
