Rose of Sharon: A Showy Summer Bloomer

8. Rose of Sharon can be invasive

Experts produce plant varieties called cultivars through selective breeding. Rose of Sharon can be invasive in some areas of the country, primarily in the southeast region. To curb its invasive nature, the U.S. National Arboretum created three Hibiscus syriacus cultivars that don’t spread: the Aphrodite, the Helene, and the Minerva. Other sterile cultivars include Azurri Satin, Sugar Tip, Lucy, Lavender Chiffon, and Diana. These varieties are widely available online or at local gardening centers.
