- The name hydrangea comes from the Greek “hydor”, meaning water, and “angos”, meaning jar or vessel. This roughly translates to “water barrel”, referring to the hydrangea’s need for plenty of water and its cup-shaped flower. (source)
- The hydrangea is the 4th wedding anniversary flower.
- Hydrangeas are one of very few plants that accumulate aluminum. Aluminum is released from acidic soils, and forms complexes in the hydrangea flower giving them their blue color. (source)
