Special Hibiscus Acetosella - Cranberry Hibiscus - Rare Tropical Plant Seeds (5) Named the cranberry hibiscus, for obvious reasons, is also known as the African roe mallow, maroon mallow , Mahogany Splendor, or red leaved hibiscus. In contrast to its tropical relatives, this rare hibiscus specimen is very hardy, enabling it to tolerate colder conditions. In addition to its stunning cranberry foliage--which resembles that of the Japanese maple--and lush pink/maroon flowers, this vigorous specimen also has larger and longer-lasting flowers than other members of the hibiscus family. Its young leaves are used as a vegetable and flowers are used to make teas and other beverages. The plant also has several medicinal applications.
