12 Beautiful Blue Flowers for Every Garden

Updated: Jun. 05, 2024

Yellows, reds, and pinks abound in the plant world, but blue flowers may seem harder to find. Try these lovely blue flowering plants.

Did you know that blue is the most popular color? It’s certainly my favorite, and my flower garden often reflects that. Blue flowers can be surprisingly hard to find, though. To me, that just makes them all the more special. I love to pair blue flowers with pink or orange blooms for a wonderful contrast. A garden full of cool white and blue flowers is also a balm for the eyes on a hot summer day.

If you’d like to add more blue flowers to your garden this year, here are some to seek out.
