There are multiple interpretations of blue hydrangea meaning, ranging from apology, remorse, understanding, and gratitude; to vanity, disinterest, and apathy. Please read on for a detailed examination of these and other important facts about the blue hydrangea.
Hydrangea Flower Etymology and Origin
Hydrangea, also known as “hortensia”, is the name of a huge genus of flowers that contain 75 different species of plants that belong to a family of the same name “Hydrangeaceae”.
These plants originated in several areas around the world, including Europe and Asia, especially Japan, China, and Korea.
The American pronunciation of the Hydrangea is [hai · dran · juh]. This word is derived from the Latin language where the word “hydro” means “water” and the word “angeion” means “vessel”.
The nomenclature of the flower comes from the shape of its seed capsule, which looks like cups that were used for drinking water.
The flower is known for its pompous shape and variety of colors. However, the colored part of the hydrangea is actually the flower sepals and not the petals like most other flowers.
Interestingly, some species of the hydrangea flower will grow with different colors depending on the level of the soil’s pH, especially bigleaf hydrangea.
The flower is also slightly toxic, as the leaves of the flower contain a glycoside compound known as “amygdalin”, which produces hydrogen cyanide, so they should be handled with care.

What Does Blue Hydrangea Mean?
When it comes to meanings and symbolism, the blue hydrangea is a strange specimen. As you’re going to see in the list below, the flower has many positive connotations but also various negative ones, so let’s explain these meanings and why they’re so contradicting:
Apology and Remorse
One of the most popular meanings of blue hydrangea nowadays is apology and remorse. This meaning is derived from an old Japanese Legend about an Emperor and the girl he loves.
The story goes that the Emperor of Japan, who was in love with a girl, became so busy with his duties as a ruler of the empire, and as a result, he neglected his beloved for quite some time.
In order to make amends for his negligence, the Emperor sent a gift of blue hydrangeas to the girl and her family.
This move made a lasting impression on the whole empire, and since then, the flower became a symbol of apology and remorse.
Gratitude and Understanding
Interpreted from another point of view, the previously mentioned story also made the hydrangea a symbol of gratitude and understanding.
In fact, hydrangea represents the abundance of all these sentiments around the world, especially in the east.
The meaning of abundance here comes from the nature of the flower and how it has so many leaves and sepals, which is also interpreted as a symbol of generosity.
Genuine Emotions
Another meaning that is also based on the story of the Japanese emperor is genuine emotions toward your loved ones.
When you send someone blue hydrangeas along with a letter that carries how you feel about them, it is a hidden message that you feel toward them is genuine and true to the heart.

Uniqueness
The color blue is quite rare in nature, and therefore, it has always been linked to its uniqueness and being special.
This shouldn’t be confused with the purple color, which is also used as a symbol of uniqueness, nobility, and royalty.
However, the purple color is used as a symbol of wealth because of how difficult it was to make purple dyes.
On the other hand, making blue dyes are rather easy, so it has a more spiritual uniqueness when compared to purple’s materialistic one.

In medieval times, it was thought that girls who grew blue hydrangeas in their yard would never find true love or get married, as the flower was associated with coldness because of its blue color, which was often associated with coldness.
For that reason, those who have been rejected by their loved ones would send them blue hydrangeas as a symbol of their apathy and cold heart.
Similarly, it was also said that if someone sends a blue hydrangea after a proposal, it means that they are not interested in having a romantic relationship with the other person,.which made the flower a sign of rejection.
Bragging
Another negative meaning that is associated with hydrangeas in general dates back to the Victorian era.
According to beliefs at the time, hydrangeas were a pompous plant that has so many flowers and a lot fewer seeds. This was a symbol of bragging with nothing to show for it, earning the flower a bad reputation at the time.
