About Hydrangeas

Notable for their big, showy blooms, hydrangeas are one of the most beautiful flowers in the world. In spring and summer, their colorful large pom-pom-like flowerheads can be seen in gardens and florist shops across the country. An ornamental bloom that has been around for a very long time, hydrangeas evoke an old-fashioned charm. Their immense florets make them great cut flowers and popular in weddings and everyday bouquets. With over 75 species and numerous varieties, the gorgeous hydrangea comes in various shapes, sizes, and colors such as blue, pink, red, purple, maroon, green, and white.

Characteristics of Hydrangea

Hydrangeas are most commonly grown as shrubs, but they can also grow as trees or vines reaching nearly 100 feet tall. Their beautiful big blooms are made up of clusters of flowers called a "corymb," which has three general forms: mophead, lace cap, and panicle. Mophead blooms have the domed, pom-pom shape most of us are familiar with. Lacecap hydrangeas have clusters of smaller flowers surrounded by larger blooms, and Panicle hydrangeas have cone-shaped flower clusters. The most widely known variety of hydrangea is called "bigleaf hydrangea," which has the lush, bountiful, rotund blooms that grace and enchant gardens worldwide.

History & Origins of Hydrangea

"Hydrangea" comes from the combination of two Greek words, "hydros," meaning water, and "angeion," meaning vessel, which loosely correlates to "water vessel." It's believed this name came about due to hydrangeas needing a lot of water to thrive, but it could also refer to the shape of their seed pods which resemble a water pitcher. In some countries, Hydrangeas go by the name "hortensia." They are native to Asia and the Americas but were first cultivated in Japan. In 1736, an American colonist introduced hydrangeas to Europe, where they have since become immensely popular.

Hydrangea Symbolism & Meaning

The symbolism of hydrangea flowers is dependent on factors such as color, culture, and time period. In Japan, hydrangeas symbolize deep-felt apology and gratitude. In Victorian times, hydrangeas had a negative connotation of boastfulness and arrogance. This meaning likely came about due to the abundance of flowers the hydrangea plant produces yet yields very few seeds. In the U.S., hydrangeas symbolize heartfelt emotion and are often given for the fourth anniversary. Different colored hydrangeas also carry their own symbolism:
