yeah the name escapes me too right now. But it is like a way to prune them but not bonsai, or the varieties of fruit trees that stay small. My grandmother had a little tree in a pot that wasn't more then 3-4 feet and it still made a good few apples each year. I can also imagine what you are describing. I like the idea of keeping it separate too so that you allow for different temperatures and just use the greenhouse section as an optional heat source. Wouldn't want to live in a jungle ALL the time. Plus yeah, the pollination is an issue, unless you stick with self pollinators only. One flower in particular, called Queen of the Night would be amazing since it only makes flower in the evening and they drop off in the morning. Little things like that, I think, would be amazing if they were more common place. Your Lodge dream is totally doable. I say go for it when the circumstance permits.
