What is a Hydrangea? Its Characteristics and Charm

Hydrangeas are flowering shrubs that bloom from June to July, representing the rainy season. They are popular flowers, available as both cut flowers and potted plants.
In recent years, hydrangeas from overseas with delicate color gradations have been sold as cut flowers and are widely used in weddings.
With their volume and stylish colors, they are highly recommended for bouquets and flower arrangements for birthdays and wedding anniversaries.
While imported hydrangeas are available year-round, summer hydrangeas are often more affordable and fuller, so if you see them at a flower shop in the summer, be sure to pick some up.

What is the Origin of the Name Hydrangea (Ajisai)?

The origin of the name hydrangea (紫陽花) comes from the Tang Dynasty poet Bai Juyi, who, upon encountering a purple flower blooming at a temple whose name he didn't know, composed the poem "Yǔ jūn míng zuò zǐ yáng huā" (I shall name you Hydrangea).
Zǐ yáng (紫陽) refers to a flower blooming in the immortal realm. When this poem was introduced to Japan, it was presented as referring to the same flower as the hydrangea, thus establishing the Chinese character name "紫陽花" in Japan.
The reading "ajisai" (あじさい) comes from an old word. "Azu" (あづ) means "to gather," and "sai" (さい) is "sa-ai," which is a combination of "sa" (さ) and "ai" (藍, indigo).

Why Do Hydrangeas Change Color?

The color of hydrangea flowers changes depending on the soil conditions. When the soil is acidic, aluminum dissolves easily and binds with the anthocyanin in the flowers.
This causes the hydrangea to turn blue. Conversely, if the soil is alkaline, aluminum dissolves less easily, and the flower color does not change, resulting in pink to red hydrangeas.
Hydrangeas are originally red, and it is the aluminum that causes them to change to blue.

What is the Language of Hydrangea Flowers?

The language of hydrangea flowers includes "fickleness," "perseverance," "fickle love," "impermanence," "family," and "harmonious atmosphere."
Because their color changes depending on the soil, they are associated with slightly fickle flower meanings.
The meaning "perseverance" comes from the fact that hydrangeas last a long time.
While many of the flower meanings are somewhat negative, "family" and "harmonious atmosphere" are derived from the way the small flowers bloom densely together.

The Language of Blue Hydrangea Flowers

The language of blue hydrangea flowers is "coldness," "heartlessness," "fickle love," "intellect," and "haughtiness." Many of these meanings are derived from the color itself.
The meaning "intellect" is said to originate from the psychological effect of calmness that the color blue brings.
Furthermore, the meaning "haughtiness" is attributed to the plant's characteristic of being beautiful but having no scent or seeds, giving it an "off-putting" impression.
A bit of a sting, isn't it?

The Language of Purple Hydrangea Flowers

The language of purple hydrangea flowers is "humility," "mystery," and "purity." Purple has been considered a precious color since ancient times, reserved only for those in power.
It is said that "mystery" and "purity" were given for this reason. Also, the deep purple color exudes a calm atmosphere,
leading to the meaning "humility." Purple hydrangeas have a mystical aura, making them popular flowers.

The Language of Red and Pink Hydrangea Flowers

The language of pink hydrangea flowers is "strong affection" and "vibrant woman." Pink hydrangeas grow abundantly in Europe due to the soil conditions.

"Strong affection" is said to be derived from its popularity as a Mother's Day gift. Hydrangeas are also popular for Mother's Day.

The Language of White Hydrangea Flowers

The language of white hydrangea flowers is "tolerance" and "sincere love." Most white hydrangeas are imported from overseas. They are frequently used in weddings.
White hydrangeas are associated with "sincere love" due to their unblemished beauty.
Additionally, white is an expansive color, creating an atmosphere that embraces everything, leading to the meaning "tolerance."
These flower meanings are perfectly suited for wedding scenes.

The Language of Green Hydrangea Flowers
