I'd love to build my trees into the garden. No benches or monkey poles or stands, but a stone wall made to resemble the mountains, a little fountain that runs like a high mountain stream, the whole pile planted with wildflowers and succulents. I'd build little nooks and shelves into the "mountain sides" for my trees.
It's a little less about the perfect tree than it is the perfect view for me. One day I'll be too old to climb the mountains any more, so I'd like to have the next best thing by the time that happens.
