Color is a powerful tool that affects how people will feel in your garden (and in any space). Are you looking for spicy excitement and vibrancy, or do you prefer a calm and peaceful feeling garden? If you are unsure of where to start, get a color wheel from an art supply store (or order one on line), and learn more about how to create the feel and look you want by selecting the right colors.
Colors appear not only in flowers, but also in foliage, stems, bark, fruits and berries. You can also compliment the colors of nature with art pieces, furniture and other accessories. If you are looking for inspiration, I suggest you look at Pinterest, seek out gardening books at the library and book stores, look through gardening magazines, walk through parks and garden centers, and pay attention walking through neighborhoods with nice gardens. There is of course more to successful garden design than just color, but it is indeed an important consideration!
