The fragrant flowers of Blue Potato Bush (Lycianthes rantonnetii, also known as Solanum rantonnetii, and Paraguay nightshade), provide a focal point to a tropical or cottage garden. Surrounded by other sun-loving tropical and subtropical perennials, annuals and bulbs, the large shrub blooms year-round in frost-free gardens. Native to Argentina and Paraguay, the blue potato bush is hardy in U.S. Department of Agriculture hardiness zones 9 to 11, which is fine for Sunnyvale.
Warning: All parts of plant and seed are poisonous if ingested.
