Well this is a fun thread. I use to try to combine tender plants but usually I didn't get the results I wanted. One plant would always take over. I have to go through your posts more slowly so I can study your combinations. I do have some pots over the years that I liked but most of them only lasted one year. One plant would win out. How do you handle your plants year to year? Do you keep them together or start new cuttings?
One reason I don't do this so much anymore also is the price of houseplants is crazy. We use to have houseplant sales in January but no more.
