Add a Pop of Color to Your Garden with a Rainbow Palette

Rainbows are one of nature’s most beautiful gifts. They hold deep significance to many and are an important symbol across many cultures. Rainbows are a sign of hope, mercy, new beginnings, and transformation. They serve as a message of acceptance and can even bring good luck! Each color within a rainbow has a special meaning too.

Revitalize your Texas landscape this spring with a rainbow garden. Planting a rainbow garden is easy, and it all begins with fabulous seasonal color! Here are a few of the best flowers for a rainbow garden.


red plants

Red is the first color in the arc of a rainbow because it has the longest wavelength of all the colors. Red symbolizes vibrancy, energy, passion, and security. It is a strong color that always captures our attention. Make a powerful statement in your landscape design or patio displays with fantastic red blooms.


Plant for the sun and explore the magic of Salvia. It has scarlet-red showy spikes that Hummingbirds love. Salvia is heat and drought tolerant and will thrive in your Texas garden.

ornamental peppers

Ornamental Peppers are striking with a tropical appeal. They are easy to care for and you can expect the vibrant ornamental fruit from mid-spring through the fall. Ornamental Peppers have bushy, glossy foliage with mini peppers that change colors as they ripen.

gerbera daisy

Gerbera Daisy is one of the best flowers for a rainbow garden. These classic blooms are quintessential for spring. They come in bright and cheerful colors to make an instant impact in flowerbeds and container gardens.

green plants

Green is the color of life. It is a refreshing color and one of our favorites! Green symbolizes growth and renewal, which is abundant in spring. It is more commonly linked to nature and living naturally. Green supports good health, recycling, and sustainability. Go green in your rainbow garden with stunning texture and a gradient of green plants!


Bring a refreshing taste to your garden with a delicious variety of herbs! Herbs are great rainbow garden plants for all seasons. They provide a wonderful fragrance and stunning foliage to any Texas garden, and they can also grow indoors on a sunny windowsill. They are very versatile because they thrive in gardens, flowerbeds, and containers. Try Mint for its oval leaves and upright growth or Oregano for its mild aroma and drought tolerance.


For a lively green accent, plant Lemon Coral® Sedum from Proven Winners® in your rainbow flower garden. It is a hardy succulent with a mounding trailing habit. It is easy to care for and thrives in full to part sun.


Get ahead of our warm weather pests such as Mosquitoes with Citrosa. This stately plant is one of the most popular perennials for this time of year because it is a natural insect repellent. It has interesting, fern-like, and fragrant leaves that smell just like citronella.



Blue and purple are at the cooler end of the rainbow spectrum. Blue represents peace, relaxation, and stability. It is a popular color with many healing and comforting properties. Purple is one of the most loved colors in the rainbow. It is associated with individuality and selflessness, and it inspires creativity and imagination.


Serena® Blue Angelonia is also known as the Summer Snapdragon because of its upright shape and delicate blooms. This sun-loving plant makes for excellent cut flowers and is a great choice for attracting butterflies to your garden.
