While blue is a common colour in the natural world, it’s not as common as other colours when it comes to flowers! Shades of red, pink and white are more commonly found amongst flowers, and these colours have become synonymous with meanings of love and devotion.
Blue flowers are associated with a sense of calmness and preoccupation. The colour represents peace, openness and serenity, and a floral arrangement incorporating blue flowers is thought to offer a relaxing antidote to feelings of anxiousness.
There are at least 20 different kinds of blue flowers, each of which is symbolic of a sense of harmony and goodwill and would make the perfect gift for almost any occasion. Let’s take a closer look at some of the most popular blooms in this hue.
Also known as Muscari, grape hyacinths look a lot like miniature hyacinths. These plants are much smaller than the traditional hyacinth and only grow to between 16 and 20 centimetres high. The flowers look like little beads strung together up and down its stem.
Grape hyacinths are easy to grow and are low maintenance. They thrive particularly in informal landscapes and are available in several different cultivars in varying shades of vibrant blue.
Morning glories bloom from the early summer months, right until the first frost of autumn. They have slender stems and heart-shaped leaves, and the flowers are trumpet-shaped. They are very colourful and as a result, attract plenty of butterflies and hummingbirds.
These plants are also drought-tolerant and grow fairly easily. They self-seed and grow in vines. Morning glories do a great job of decorating pergolas or arches, as well as serving as a dense groundcover. Also with asters, morning glories are the September birth flower.
