Afraid I have neglected this thread a bit of late as with the daytime temperatures here still over 30 and no sign of rain on the horizon finding plants in flower is no easy matter. However, the following plant does flower for most of the summer even with limited water, although not so profusely as during the cooler months and with smaller individual flowers. I've always known it as Solanum rantonnetii but it seems I now have to learn to call it Lycianthes rantonnetii.
