Alan it appears you and I are on a similar mission. I replaced a part of the yard already with multicolored granite chips, and I found that some of the white quartz that was also left behind here looks quite nice mixed in with the granite, here and there. I will post a picture or two.
What are the two flowering trees you have left in place? I am heartened to see this since I intend to leave two Plumeria trees in place. Here is a picture of the work in progress.
Of course the two big Pachypodiums are staying, and the Yucca elephantipes. Everything else is still open to being moved. I am at the moment creating some undulating hills and hope to have some rocks to display.
