Are you ready to turn your garden into a joyful explosion of color, this time using colors in groups of three?

If you want to color your garden HAPPY with the bright and bold… Imagine vibrant reds that spark passion, bright yellows that radiate sunshine, and cool blues that whisper calm and ground the palette… all dancing together in your flower bed.

This bold, high-energy palette isn’t just eye-catching… It invites bees, butterflies, and big smiles to your yard. You’ll often see these colors together in children’s gardens, buzzing pollinator patches, and the hottest summer plantings. Welcome to the Primary Colors garden.

If you’re craving the more unexpected, artistic, and nurturing combo… Meet the trio of orange, green, and purple- a color combo that is equal parts drama, balance, and whimsy.

Orange brings the energy, purple adds a regal touch, and green grounds it all in lush calm. Together, they create a contrast that is striking, wild, and wonderfully coordinated. You’ll see this fearless palette pop up in edible gardens, modern landscape designs, and anywhere creativity blooms. Welcome to the Secondary Colors Garden.

Want to bring one or both of these combinations to your garden? Let’s dig in…

In this creative approach to planting the color wheel, a key in each combination is to pick a dominant color that is bright and eye-catching, and use the other two as accent colors. It’s clean and cohesive this way, and acts as a visual anchor for your eye! If there are too many bold colors, it can feel overwhelming. For example, yellow makes a great builder color! Since yellow is the brightest and most eye-catching of the three primary colors, it’s an ideal dominant color for this garden. You can then accent the yellow with smaller sections of reds and blues. Here’s some design tips for each combination, and more favorite flowers in each color! Combine both annuals and perennials for the best variety. Let’s dive into each combo! 

The Classic-but-Bold Primariesd

Bold, playful, and with high energy, the passionate reds, sunny yellows, and calming blues come together to transform your outdoor space. This garden color scheme practically throws a party in your backyard! This classic combo never fails to shine.

Dominant Color: For primary’s dominant, choosing yellow or blue is ideal. Red is visually intense, and also advances visually (meaning it appears closer), so it may make a garden feel smaller.
