I have kept these in pots in a warm conservatory and as long as you feed and water it should repeat flower. I'm pretty sure they can't live outside in Uk anyway and think they need to be above a minimum of 45 degrees inddors too.
Agree... most people kill indoor plants through over-watering.
Orchids, for example. They just need a fine spray on the foliage and exposed root structure .. that's it!
thanks for all the information. I forgot to say my stephanotis although labelled as high]ly scented, has hardly any perfume and keeps droppi ng it's flowers
