From Better Homes and Gardens and Town and Country Magazine, did you know:

Hydrangeas are allergy safe flowers. Hydrangeas are unique because they have super sticky pollen. That makes it difficult for wind to blow the pollen around, making these flowers perfect for allergy-prone gardeners. They’re also fragrance free, which makes them a great addition for those who are headache prone or have sensitive noses.

Believe it or not, you can tell a lot about hydrangea plant care by its name. Hydrangea is from Greek descent: “Hydro” means water and “angos” means jar or vessel. And in fact, hydrangeas need lots of water to thrive.

There are around 70-75 species of hydrangea.

Hydrangeas are actually toxic! The compounds in the leaves release cyanide when eaten, so keep the plant away from small children or pets. Although they’re poisonous, it’s reported that ancient Buddhists used the roots as an antioxidant in tea to cure kidney issues—but don’t try this at home!

Actress Blake Lively used pink hydrangeas in her wedding bouquet.
