Solanum pseudocapsicum
Solanum pseudocapsicum is a nightshade species with mildly poisonous fruit. It is commonly known as the Jerusalem cherry, Madeira winter cherry, or, ambiguously, " winter cherry". These perennials can be grown decoratively as house plants, but in some areas of South Africa, Australia and New Zealand it is regarded as a weed.
