How to Grow Blue Potato Bushes
The sweetly scented flowers of Lycianthes rantonnetii, also known as Solanum rantonnetii, blue potato bush 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.
