Agree with both! All of my plants go outside for summer too. It is the plants that can grow normally inside all of the time that I consider house plants. But not all houses have the same conditions. Those that can't do well in an average house, I would hesitate to call a house plant, but that's such a gray area, slippery slope, and can't really be quantified. Even "grow normally" could be debated, with many valid points on several different sides. For example, some might absolutely love a Brugmansia plant even if it could never make blooms, where others might prefer to have something else that could easily make blooms instead in the same conditions. It's very subjective, and I appreciate the discussion about it. Folks can read the anecdotes, the conditions that produced them, to compare them with the conditions they have, plants that interest them, and be more able to decide if a particular plant in a particular location would work for them, and how to give it a try.
