Here I am offering you a Gallon Plant of Hibiscus moscheutos Blue River II, also known as Hardy Hibiscus, Rose Mallow, and Swamp Mallow. This gorgeous shrub has huge 10 inch blossoms that are the center of attention when they are in bloom. Hibiscus Blue River II grows 5 to 6 feet tall. Dying back in my zone 8B garden, they come back even larger the next summer. Hibiscus Blue River II needs a few hours of sunshine each day to blossom well. USDA Hardiness Zones 5 to 9a
