According to the Association of Societies for Growing Australian Plants, the most commonly cultivated member of the Alyogyne plant in the United States, including California and the West Coast, is the Alyogyne huegelii. Otherwise known as the blue hibiscus, Alyogyne huegelii is neither blue nor a member of the hibiscus family. The flowering shrub features purple, white or rose-colored blooms and, if properly cared for, can grow to about 6 feet in height and breadth. Ensure your Alyogyne huegelii thrives by providing it the proper amount of sunlight and wind protection.
