Two fresh new perennials that you do not want to overlook are the hardy hybrid hibiscus (say that three times fast!) Introducing Midnight Marvel and Starry Starry Night. These shrubs are bound to grab attention with their large blooms and dark purple foliage. Scarlet-red flowers open from round cups into plate-like blooms on the Midnight Marvel. In contrast, the Starry Starry Night bears light pink flowers with red veining, also blooming into flat discs. Unlike other hibiscus cultivars, flowers are produced from top to bottom of the shrub. Growing to be about 4 feet tall, these hibiscus will bloom continuously in full sun until the first frost.
