Perhaps a new category is needed. One for container grown plants where the emphasis is on the plant and how it's grown rather than the container itself. I do that a lot. I don't consider very many growing in containers as houseplants except as a requirement to keep them alive through the winter until I can get them back outside in the spring. I only have one plant that is inside year 'round. I also grow a lot of plants in containers that can survive the cold better than the clay containers they're in and which are being grown in a container by choice but could also be grown in the ground. Growing in containers is a style of growing, just as making a garden bed directly in the ground. IMO, of course
