15 Brilliant Blue Flowers for Your Garden
Finding plants that display true blue blooms can be a daunting task for gardeners. While numerous plants are marketed as having blue flowers, in reality, their blooms often tend to lean towards shades of lavender or purple, rather than a pure blue hue. Moreover, the perception of color can be influenced by sunlight, leading to variations between the blooms depicted in seed catalogs and those observed in your own garden. However, despite the challenges, there are indeed blue flowers available for those who are determined to add this elusive color to their garden.
1: Cornflower (Centaurea cyanus)
This is one of the most artistic and beautiful blue flowers. Centaurea cyanus, commonly known as cornflowers or bachelor’s buttons, exudes a captivating charm as a wildflower. Its name “cornflower” originated from its natural occurrence in European cornfields, while “bachelor’s button” was inspired by the tradition of bachelors adorning the flower in their lapels during courtship. The plant boasts an abundance of ruffled disk-like flowers, resembling thistles in appearance but without the prickly thorns. As an annual, Centaurea cyanus has the remarkable ability to self-sow, ensuring its presence in the garden year after year. On the other hand, the mountain bluet (Centaurea montana) is categorized as a perennial cornflower, offering enduring beauty and longevity to any landscape.
2: Poppy Anemone
This is one of the most attractive blue flowers. The poppy anemone, also known as Anemone coronaria, is a captivating flower that adds a touch of elegance and charm to any garden or floral arrangement.
