The history of hydrangeas

Though hydrangeas were first discovered in Japan, hydrangea fossil records (yes, there are plant fossil records!) show that they were actually growing in North America 40-65 million years ago. It’s believed that they existed millions of years ago, but eventually became extinct in North America. Or at least, they were until 1736, when a European colonist brought them to the New World. While this may be the more historic account of how hydrangeas came to the United States, a small town in Illinois believes in a different story.

Local legend has it that a woman named Harriet Kirkpatrick was riding on her horse through the woods of Illinois when she discovered hundreds of white Annabelle Hydrangea bushes in full bloom. Thrilled by her discovery, she went back home to find her sister and show her these magnificent flowers. After the two transplanted them into their garden at home, word quickly spread throughout the town of these “snow-like” plants. Within days, everyone in town had hydrangeas growing in front of their home.

Hydrangea symbols and meanings

Depending on the culture, hydrangeas have held many different meanings.


In ancient Japan, it’s believed that whenever an emperor did something wrong, he would apologize to his maiden with hydrangeas. Therefore in Japan, hydrangeas typically symbolize sorrow, regret, or an apology.


It turns out that in Europe, you don’t exactly want to be given hydrangeas, as they are left at the homes of people who are arrogant and rude.

The United States

In America, hydrangeas have much happier meanings. Most commonly, they’re associated with familial love and are one of the most popular flower choices for Mother’s Day. They’re such a popular flower, that each color holds its own significance.

Hydrangea care

The word “hydrangea” comes from the Greek word hydro, meaning water. The name was inspired by the constant water that’s needed to care for them. In addition to plenty of water, here are a few other things you should know about caring for hydrangeas:

  • Hydrangeas can thrive in full-sun or partly shady areas.
  • They should be planted in rich, moist soil.
  • Soil pH greatly affects their bloom and coloring, so make sure your soil isn’t too acidic.
  • Hydrangeas can live for years without needing to be pruned, however if you do decide to prune them, you should do it before midsummer.
