Top 10 Most Beautiful Blue Flowers

Blue carries a quiet beauty, a natural cool hue best suited for the hot summer. Yet, blue flowers are rare in nature.

Do you know what they might be?

I present to you the top ten most beautiful blue flowers, including irises, snowflakes, cornflowers, bluebells, gentians, endless summers, and delphiniums. Let’s take a look together.

1. Iris, the National Flower of France

Among blue flowers, the most famous is the iris, the national flower of France. The name “Iris tectorum” comes from the Greek word for rainbow, suggesting that the colors of the rainbow can be found within this flower.

In China, irises often symbolize love, friendship, and limitless potential. With a corolla made up of six petal-like leaves, three or six stamens, and a pistil wrapped in a pedicel, the flower resembles a dancing butterfly.

In May, the iris blooming season, you can see these “butterflies” flitting among the green leaves, seemingly spreading the news of spring.

2. Snowflakes, a flower featured in the Beijing Olympics

Among various blue flowers, snowflakes have always been extremely popular. With a long blooming period, they can be grown in gardens or used as potted plants to decorate balconies, making them a promotable variety for both gardens and homes.

The flowers of the snowflake are a fresh and romantic sky blue, resembling delicate snowflakes. Their long viewing period, deep green leaves, and elegant flower colors provide a cool feeling during hot summers.

They were one of the superior ornamental flowers used to decorate Beijing during the Olympics.

3. Cornflower, the National Flower of Germany

The cornflower is considered one of the most beautiful blue flowers. Originally a wildflower, it has been cultivated by people over the years to become less “wild,” with larger flowers and more color variations including purple, blue, light red, and white.

Among these, the purple and blue are most valued. With its lovely colors, beautiful shape, fragrant aroma, and robust vitality, it’s adored by Germans and has been chosen as their national flower.

The blue cornflower is a very deep blue and can be grown from seeds or used in flower arrangements.

4. Bluebell, the Most Popular Flower in the UK

When considering beautiful blue flowers, many people will think of the bluebell, known for its highly distinctive shape, often referred to as a “fairy’s bell.”

This species is widely cultivated in Western gardens and used in forest or flower bed layouts. They bloom at the same time as hyacinths, daffodils, and some tulips, but due to their strong propagation ability and rapid spread, they need to be carefully controlled like weeds.

In spring, bluebells bloom a cluster of fragrant, bell-shaped small flowers that are blue-purple. In their native habitat, swathes of bluebells create a beautiful blue-purple flower carpet. The bluebell is also recognized as the most popular flower in the UK.

5. Gentian, the Elf of the Plateau

The gentian, also known as the elf of the plateau, once densely populated cliffs, sprawling across hillsides, between clumps of grass, and in rock crevices.

Tender buds emerge from their developed root systems, sprouting thin stems and pairs of leaves that paint the cliffs with exceptional beauty.

Growing far from bustling towns, in a world with pure air, the gentian seems unsullied and noble. Its unique blue color, reminiscent of an untamed elf’s call, offers a sense of enlightenment and insight.

6. Endless Summer, a Blue Hydrangea

Hydrangeas, with their full, large, and beautiful blooms that range in color from red to blue, are a feast for the eyes and a common potted ornamental plant.

Among them, the Endless Summer variety is highly praised and quickly became popular worldwide after its introduction. This variety is greatly influenced by soil acidity and alkalinity levels.

Adding ferrous sulfate, magnesium sulfate, alum, or lime can result in blue, purple, lime, pink, or red flowers. Its greatest feature is its ability to bloom repeatedly.

In some places where winters aren’t too cold, Endless Summer can even bloom in winter. The blue Endless Summer in particular is elegant and pleasing to the eye in the summer.

7. Delphinium

Also known as the larkspur, the delphinium is so named because its flowers, predominantly in shades of blue or light purple, resemble blue swallows alighting on branches. Hence it is also called the “swallow herb”.

It’s a precious resource among blue flowers and highly valued for its ornamental appeal.

As one of the “three musketeers” of the garden, along with foxglove and hellebore, the larkspur’s erect flower spikes can produce dozens of blooms and represent one of the few linear flower varieties in gardens.

8. Blue Butterfly

In my opinion, the Blue Butterfly is the most beautiful blue flower. When in bloom, it resembles a group of butterflies dancing elegantly, hence its name. It looks lightweight and adorable, with delicate coloring, making it an excellent ornamental shrub.

It generally blooms in the spring and summer, with the blossoms extending from the tips of branches and unfolding successively over a long blooming period. It needs to overwinter indoors and is a beginner-friendly plant to care for, which makes it very suitable for novices.

9. Grape Hyacinth

Despite its name, the Grape Hyacinth actually belongs to the lily family. This is a highly ornamental perennial plant with neat, low-growing plants and dignified flower clusters. It’s beautiful, colorful, and among the most eye-catching blue flowers in the garden.

The Grape Hyacinth is one of the most beautiful blue flowers. It looks serene and elegant against the backdrop of glossy, tender green leaves and is a well-known perennial that blooms early in spring. In addition to blue varieties, Grape Hyacinths also come in pink and white.

10. Blue Star Flower

Among blue flowers, the Blue Star is also very popular. The Blue Star has a blue corolla, with a white star-shaped center and white star-shaped stripes on the back, giving it a fresh and refined look. Its flowers are small and brightly blue, and it can bloom all year round, especially in spring and summer.

It’s perfect for planting in residential areas, campuses, courtyards, parks, and office areas for greening and beautification. It appears lush with elegant colors, resembling numerous twinkling stars, making it extremely unique.
