Ideally, people should add comments for the plants they own. It's a tall order for people with lots of different plants, however, so it may never happen in some cases, but as time goes by, we should have comments from various locations for the same plant.
Maybe we should all start posting comments for the plants on our lists -- just a few a day, so that it doesn't turn into an onerous chore. We can state how well the plants do in our locations, under our specific gardening conditions, and mention the special care we have to take with some plants.
