A friend of mine in Singapore bought this thinking it's a tomato, but it isn't. Any ideas? Thanks, Newt
Could be Solanum capsicastrum. See pic at http://deambarino.bavarian-petcare.com/medizinisches/giftpflanzen/korallenbaeumchen.htm The fruits may be unripe, but I think there are also yellow-fruited forms.
Or the very similar Solanum pseudocapsicum (not quite sure what the difference between them is). Both have slightly poisonous fruit.
