Are Hydrangeas Poisonous to Human and Pets?

Hydrangeas are lovely plants with colorful flowers. They are common in gardens. But are they safe for pets and children? Hydrangeas have toxins that can harm humans, dogs, and cats. Luckily, serious harm is rare.

Hydrangeas change color depending on soil. Red flowers grow in neutral or basic soil, while blue or purple flowers grow in acidic soil. This adds to the beauty of the plant.

Let’s look at the risks of hydrangeas and how to keep everyone safe.
