I have a question about this house plant - see picture. Forgot the name... Anyway, I had it and it looked very pretty, until it lost all the leaves except the ones on the top. It has been like this for years, but it looks more and more depressive. It started to get new leaves at the bottom. So my question: should I just cut of this long stem, put it in water for a while and see if it roots or should I just be happy that his plant is still alive?
