Hydrangea History + Origins

The hydrangea was first cultivated in Japan and is often referred to as Ajisai. The flowers bloom during the rainy season (tsuyu) from June to July and turn places like the Meigetsuin Temple into a mystical, fragrant garden. The Japanese are famous for their mesmerizing gardens and revolving stories around their flowers. The hydrangea is no exception: legend has it that a Japanese emperor gifted blue hydrangeas to the family of a girl he loved to make up for neglecting her.

Not only the Japanese have enjoyed the sweet scent and vibrant colors of hydrangeas for centuries, ancient fossils dating back to 40-65 million years ago show that the plant has also been growing in North America for quite some time. In Europe, hydrangeas didn’t appear until 1736, when a colonist brought a North American varietal to England. Today, hydrangeas can be found all over Asia, the Americas and Europe, where they are mostly known as hortensias.

Hydrangea Meaning + Symbolism

The etymological meaning of hydrangea stems from the Greek words for water, hydros and jar, angos. It was given to the plant because of its shape resembling an ancient water pitcher. How fitting, since hydrangeas require constant moisture to stay happy, healthy and blooming.

While everyone seems to agree that hydrangea care includes a lot of watering, the symbolism of the flowers varies drastically between cultures. In Japan, the flower is associated with heartfelt emotion, understanding and apology. The Japanese emperor apparently made a lasting impression not only on his girlfriend’s family but also the rest of his empire. The hydrangea can further symbolize unity and togetherness.

Contrastingly, hydrangeas have a negative sentiment in Europe where they were used to declare arrogance and boastfulness. This association is based on the ability of the plant to produce many flowers but very few seeds. English men in the 1800s used to send hydrangeas to women who rejected them, accusing them of frigidity. Thanks to the Victorian men’s poor attitude and lack of empathy, it is believed that young women who grow hydrangeas in their front yard will never get married. In other words: if you’ve been unlucky in finding a partner, maybe you should check your grounds for hydrangeas.

Hydrangea Meaning by Color

While hydrangeas symbolize different things across cultures, the meanings of the distinct colors are mostly uniform around the world. When you’re looking for the right hydrangea to express your feelings or intentions, no matter where you are, make sure to pick the right color.
