I can't answer those questions yet, Jorun, as it is a new acquisition. Last week we visited one of the few nurseries on the island that we trust, they specialise in herbs and small perennials. The owner, who is a botanist and geneticist, along with a string of other ...ists, one of which she has a PhD in, is presently concentrating her efforts on salvias. We had a long conversation with her on this subject and along with the car boot load of plants we purchased she gave us this Pentas to try out. It's currently in the ground not far from our kitchen door where we can keep an eye on it so I'll try to remember to let you know how it survives the winter and next summer. I have to admit that the last one I tried, several years ago, only lasted the one season.
