JB: Thanks for chiming in. I am pretty, very sure that mine is a Jasmine Confed (see pic when bought on mid sept) and not a camellia.
When you said: "I had to defend my favorite fragrant houseplant" I was encouraged again. But not sure I can be happy when you say: "I brought in all my jasmine, both the Maids of Orleans and the Royal and Star and not one lost any leaves yet." Maybe it's a hint that I did not do everything right for my jasmine. Would you be kind to share your experience, point out my fault and offer some remedies? Thanks
