We have one here at work and we dont know how to care for it. 1 Answers 0 Vote Up Vote Down Gerry Daly Staff answered 7 years ago It is probably a Christmas cherry. Solanum capsicastrum, if you look this up. Keep it in a bright place, not too much direct sunshine, keep just moist and feed every two weeks between April and September with a houseplant food.
