I cannot answer questions about difficult and rare houseplants but I can with all the rest of the popular or even uncommon types.
I have grown houseplants for a lot of years and as always, I started off with a cactus and a Chlorophytum. I know all about the growing conditions, watering, feeding, humidity and propagation. I also know about the winter care and the pruning of flowering houseplants and the lighting for the foliage plants. I can also tell people the difference between pot plants and permanent plants and how to keep the pot plants for another season if that is possible for that particular plant.
