Although you could opt for a flower garden that blooms in a single color—like all white or all green—showing off the rainbow of shades that nature offers is a more cheerful and vibrant option.

With more than 400,000 types of flowers in the world, there's no shortage of colors and textures you can add to your yard: Purples and blues so dark they look black, fire-engine reds and lemony yellows, neon pinks and lime greens. Gardening experts share some of their favorite bright blooms to inspire your next garden masterpiece.
