Does this plant fit my garden? Set up your Plantfit profile →

Perennial plants with blue flowers evoking calmness, freshness, the charm of wild flowers, and seaside vacations... Quite rare in gardens, this colour nevertheless offers a wide range of shades. Shades include a soft and discreet blue with the Blue Star Columbine or the Perennial Geranium Nodosum, a more intense blue with Delphinium Belladonna Bellamosum or a simply legendary blue with the Blue Himalayan Poppy. In shade or in the sun, in a flower bed or in a pot, blue goes perfectly well with white, but also other colours. It also forms a happy, complementary union with yellow and even with pink when it takes on a lavender hue and is accompanied by greyish foliage. Whether your garden is classic or "experimental," discover our wide range of perennial plants with blue flowers, and you will undoubtedly find the one you are missing!
