When you get right down to it gardens are really about color. That color can come from flowers, foliage, bark, pottery, furniture, fences and even artwork, but in the end it is all about color. Our gardens are meant to enhance our lives and to make our homes look better from the curb. Color can be soothing or exciting, it can be a riot or a river, it can be front and center or something much more subtle, but whatever our choices, color is the goal. Any color scheme can work, it's your garden so if you're happy who cares what anyone else thinks. However, understanding the basic principles of using color in design can help make that picture in your head a reality. Be it a soothing sanctuary or a patio ready for a party.

Why Neutral Colors are Important in the Garden

The first thing to learn is which colors are considered neutral in gardening. Neutral colors are those colors that can be used with any other color without changing the effect that you are trying to achieve. White, black, grey, silver and shades of brown are considered neutral in any arena. In gardening, green also functions as a neutral. Neutral colors will have a tendency to tone down the other colors in a bed and can be used as a buffer between two plants that might otherwise clash.

While white functions as a neutral in the garden, it also serves another purpose. White glows when you view the garden early in the morning, during the evening and at night. With busy lives, many of us view our gardens less during the day and more often during twilight hours. If you will be using your garden often after dark be sure to include a healthy dose of white flowers and silver foliage. These plants will show well in the evening.

Pick a Garden Color Scheme

The easiest color plan to pull off is probably the monochromatic color scheme. Which is simply combining shades of a single color together to create a garden bed. These beds are simple to put together because choosing plants from a single color family is pretty easy to do. I know monochromatic can sound boring, but these beds don't have to be blah. They can include great depth and interest as illustrated in the photos below.

  • Monochromatic color schemes include shades of red including pink, shades of orange, and shades of yellow.
  • Other monochromatic color schemes include shades of black, white, or violet.

How to use the color wheel for plant combinations

Now comes the part that can be a little bit more intimidating, mixing different colors together. Mixing colors doesn't have to be difficult and learning to successfully mix colors is easiest if you use the color wheel as a starting point. I know just hearing that you might be using a color wheel may strike terror in your heart, but take a deep breath and repeat after me "The Color Wheel Is My Friend." Really.

The first key to understanding mixing colors is to look at the basic relationships between the colors. Using the color wheel is the easiest way to illustrate these concepts. One easy way to combine colors is to use analogous colors. Analogous colors are those that are next to each other on the color wheel. These colors tend to blend together well. The diagram below shows the 6 major colors on the color wheel. Analogous colors include red and orange, orange and yellow, yellow and green, green and blue, blue and violet, and violet and red. Analogous colors can go beyond two colors, groups of red, orange, and yellow or blue, violet and red can also be considered analogous colors.

Here are some photos that illustrate use of analogous colors in the landscape. The photos below show: violet and red, red and orange, orange and yellow, and green and blue color schemes.

If you are a bit more adventurous and like some contrast in your colors, try using complementary colors, which can add a lot of pop to your bed. Complementary colors are opposite each other on the color wheel. The diagram below shows the different complementary colors. The 3 complementary color pairs shown here are violet and yellow, red and green, and orange and blue.


Here are some photos that illustrate the use of complementary colors in the landscape. The color duos below are orange and blue, violet and bright yellow, and violet and light yellow.

The third color scheme illustrated by the color wheel is the color triad. The color triad is created by drawing an equilateral triangle connecting 3 colors in the color wheel, see the chart below. In our illustration red, yellow and blue are a triad and violet, orange, and green are a triad.

For a real life example of each triad, look at the photos below. The photo on the left illustrates the red, yellow and blue triad while the photo on the right illustrates the violet, orange, and green triad.


Dark vs. bright colors in the garden

Colors also fall into two different categories, dark and bright colors. Dark colors, like blue, purple and pink, tend to create a calming and serene atmosphere and will appear cool in even the worst heat. Dark tones are perfect for creating a sanctuary, where you can go to unwind and de-stress from the chaos of life. These colors are great for setting the mood for gatherings filled with soft music and quiet conversation. 

Dark colors also have a tendency to make areas look larger than they are. If you have a small garden these colors can help make your area feel more spacious. Don't forget that neutral colors will work with both dark and bright colors to expand the palette of plant material while maintaining the mood you are creating. Here are two examples of gardens using dark colors:


Bright colors draw attention and make spaces seem smaller. If you have a large space and you would like to make it seem smaller use bright reds, oranges, and yellows in the distance. This will make the planting seem closer to you. Bright colors are also great for drawing attention to areas you would like to highlight, for instance: a front entrance, featured flower beds, seating areas, or artwork. Bright colors add a festive feeling and put you in a party mood. They are good next to the patio or a deck where people tend to gather for entertainment. Here are two examples of gardens using bright colors:


I have always tended to be attracted to bright colors, but I was a bit timid in how I mixed those colors together. I tended (still do to some extent) to be most comfortable combining analogous or monochromatic colors. Then several years ago, I had a bit of a color epiphany, brought on by a giant corally-pink wall that we installed in a garden we use for a trade show. While I love the color, we used a paint color match system to duplicate the color of my winter coat. I wasn't so sure a 15 foot tall, 100 foot long, wall painted that color was the best idea. However, after painting the wall and placing almost every color imaginable, including salmon, in front of it I realized that you should never be afraid of bright colors. A wider range of colors than you might think will work together, a fact I have to keep telling myself.


A huge, bright coral-pink wall might be a bit of overkill, although pretty fantastic; bright pink chairs might just fit the bill.  If you are afraid that you might get tired of the color, don't worry. A simple coat of paint changes everything. By now the wall has been at least 5 different colors and the chairs have to be on at least their 10th coat of paint. A coat of paint changes everything, from a bright pink party to a soothing blue sanctuary in a few simple brush strokes. OK, make that a few gallons of paint.


One last point, the most important thing is that you love your garden. If you have to leave these color principles behind to create your dream garden, do it. If you're happy, other opinions do not matter.
