Every time I go to a new nursery, I find something new and wonderful. The only way I have been able to hold myself back is to limit my selections to to plants that should only be a foot tall or less to fit the scale of the Japanese garden. Recently I discovered Dwarf Mondo Grass. The tag says it could be eight inches at maturity. Bingo! So once I planted it I could hardly seeing in the garden so I started looking for light colored rocks and now there is a sweet contrast between the plant and background.
