Cosmos Flower Meaning

The beauty of the brightly-hued daisy-like cosmos flower is undisputed, but is there something more to it? What sets this blossom apart in the far-reaching world of blooms? Read on to find out the meaning of the Cosmos flower and why everyone should grow it!

What is a Cosmos Flower?

Known as the “autumn cherry blossom” in Japan, cosmos is a genus of flowering plants belonging to the Asteraceae family. This includes other iconic flowers such as daisies, sunflowers, dahlias, and asters.

Inspired by its perfect, even-placed petals, this sun-loving plant gets its name from the Greek word “kosmos,” which means world, order, and harmony. Native to Mexico and southern parts of the US, it can grow up to a majestic height of 6 feet.

Its heart-stealing blooms take center stage with saucer-shaped, perfectly aligned petals appearing in hues of white, pink, and crimson anytime from late spring to fall!

The Journey of Cosmos Flowers

The Journey of Cosmos Flowers

Celebrated as the cherry blossoms of fall (akizakura) in Japan, these flowers spread from the Americas to Europe during the Age of Discovery around the 16th century, when European explorers discovered and fell in love with the soft and silky cosmos flower.

These easy-growing self-seeders were so adept at adapting to different habitats that as trade routes expanded, they didn’t just stay in Europe. From the 19th century onwards, they found loving homes in Japan, Korea, China, and other nations of Southeast Asia, and today, they are found in gardens all over the world!

Now that you know where they came from and how they spread, let’s dive into how the cosmos has inspired humans to find ways to endear themselves to its flawless blooms.

Given the meaning of its name, when someone gifts you a bouquet of cosmos flowers, they’re saying, “You mean the world to me.” Its star-like symmetrical petals also enhance its celestial and cosmic appeal.

And it’s no coincidence that cosmos flowers traditionally share October as their birth month flower with the iconic Marigold. October symbolizes change and evolution, so cosmos flowers have also come to signify new beginnings.

In Europe during the Victorian Era, amidst the popular practice of floriography (conveying messages and emotions through flowers), they symbolized joy and love. Victorians related the symmetry and balance of the blooms with a wholesome relationship.

Back in its home of Mexico, these flowers divined a harmonious union between humans, nature, and God. They are often used to call upon the spirits of the departed and used in the famous Day of the Dead festival.

These flowers are said to represent intangible aspects such as peace, tranquility, innocence, modesty, and joy. Being so resilient, they bless the most hostile environments with their blooms and signify the ability to rise above all obstacles!
