Asa respected members, I am floating a suggestion for the senior members as well as those who have graceful gardens! It would be great for all of us to see your plants that have grown old and beautiful. Your pictures would show us how you trained and shaped your plants eg Dr arif's wisteria. They might show how you pruned again and again to achieve the perfect Niwaki or Pom poms! Or how beautiful the aged trunk of your bottlebrush looks. Or how overpowering the fat adventitious roots of your old ficus tree have become.
Hope this suggestion produces some inspiring posts. For me the best payback of any garden is to see it age!
