Hibiscus 'Heartthrob' has stunning deep red flowers with very dark red centers and dark veins. The flowers are the size of dinner plates, measuring 8 – 10 inches across when fully open. The petals are overlapping and very slightly ruffled. The plant grows to 4 feet high and blooms in mid summer to early fall. It is attractive to hummingbirds and bees while resistant to deer. The name Hibiscus came from the Greek work ‘hibiskos” that meant “marshmallow.” The sticky root or stem of some plant in the mallow family was used at one time to make marshmallow confections.
