Beautiful Blue Flowers of Summer

We love summer flowers for their vibrancy, rich hues, and the vast array of poppin’ yellows, oranges, reds, pinks, and whites. Often hidden in the sea of brightly-colored blooms, summer’s lovely blue flowers command attention in their own right by complementing rather than competing with showier blooms. You can find blue flowers in a variety of shades ranging from baby blue, royal blue, navy blue, indigo, and blue-violet. 

In the language of flowers and color symbolism, blue represents serenity, tranquility, intelligence, and spirituality. Blue flowers evoke feelings of calmness and peacefulness and can promote relaxation and contentment. Coming home to a beautiful bouquet of blue flowers after a long day is a great way to decompress and enjoy their beauty. Blue flowers are very versatile and pair well with any other flower color, whether bright, dark, warm, or pastel. 

If you’re ready to experiment with blue flowers, here are some of our favorites we love designing with.
