Color gardens are fun for adults, but they can also be educational for the kids. Creating a rainbow garden theme is an easy process that will help spark interest in these little gardeners. Let's learn more about some rainbow garden designs that you can use for teaching your children their colors and more.

How to Make a Rainbow Color Garden

A color garden is created just like any other garden design. Select rainbow garden plants that grow well in your area and be sure those chosen share similar growing requirements when planted together. You can also grow different types of plants in containers for more flexibility. Help your child pick plant colors that will complement one another as well as the overall design to avoid looking too busy, and choose age appropriate plants too. Include plants with various sizes, shapes, and textures to maintain interest. Have your child create whimsical décor that can be placed throughout the garden as well.

Ideas for Rainbow Gardens

When it comes to color gardens, there are many possibilities. Let your imagination run wild-- taking clues from your child-- and don't be afraid to experiment. After all, isn't that what gardening is all about? If you need a few inspiring ideas to get you started, the following suggestions will help:

Edible rainbow garden

Using fruits and veggies from all colors of the rainbow, create an edible garden. For added interest, shape the garden like a rainbow or in a circle with rows or spokes of like colors grouped together. Keep the tallest plants in the center and work your way down. Choose companion plants that will grow well together (i.e., yellow squash growing up or around yellow corn stalks, red radish growing in front or next to red tomatoes). This list of colored edible plants should help too: Blue/ Purple: blueberries, eggplant, blackberries, grape Pink/Red: strawberries, tomatoes, watermelon, radish, beets, raspberries, red pepper Yellow: squash, banana pepper, sweet corn, rutabaga White: cauliflower, onion, potato, white corn, parsnips Green: green beans, asparagus, cabbage, broccoli, zucchini, green pepper, cucumber Orange: pumpkin, sweet potato, cantaloupe, butternut squash, carrot

Flowering rainbow garden

Create a small garden plot filled with colorful flowering plants. Have your child add decorative signs, labeling each color. Older children can also include the plant names. Here are some good flower choices for each color: Blue: bellflower, aster, lupine, columbine, baptisia Pink: astilbe, bleeding heart, fuchsia, foxglove, petunia, impatiens Red: petunia, cockscomb, geranium, dianthus, rose, snapdragon, tulip Purple: violets, iris, grape hyacinth, purple coneflower, purple fountain grass Yellow: sunflower, marigold, coreopsis, chrysanthemum, goldenrod, daffodil White: sweet alyssum, Shasta daisy, moonflower, candytuft, nicotiana Green: jack-in-the-pulpit, green coneflower, green calla lily, hellebore Orange: poppy, nasturtium, marigold, daylily, zinnia, butterfly weed

Rainbow color groups

For this one, use a color wheel as your guide to group like colors or color temperatures together. For example, blue, purple, and green plants are considered cool colors while yellow, orange, and red ones are warm or hot. Don't forget about the neutral shades: white, gray, and black. Include all plant types for this design, flowering, edible, and foliage. Here are some plants with colorful foliage:

Rainbow garden art

Have your child create colorful displays throughout the garden. Anything from mosaic artwork and steppingstones to colorful planters and signs will add that extra “zip” to the garden.
