By using yellow in the garden you can make the garden appear bright and vibrant. Yellow is happy, cheerful, optimistic and uplifting. It goes well with green, the dominant color inmost gardens, and looks terrific when accented by orange. Yet it provides a good companion for blue, purple, and red. Yellow’s versatility makes it a very friendly color for many different kinds of gardens.
