That will depend on what "style" or "feeling" you want in the area. For example Cadillactaste has a very nice landscape suitable for a wide variety of plants where someone like myself looks to have a Japanese inspired place AND in addition a Wabi Sabi approach. They are both nice to the eye but you have to decide as you are the person that sees it and takes care of it. Any garden design needs to be done with the owner and anyone else involved in the project for success - Just my opinion, but at the old place I had 3 show gardens and was inspired by Japanese tradition and the work of Ben Oki here in the USA. I need a personal space that says nothing but "sit, enjoy, relax" nothing more nothing less.
