Yarrow is a popular plant in many home gardens. It is known for its beautiful clusters of tiny flowers and feathery leaves. Gardeners love yarrow because it is easy to grow, drought-tolerant, and attracts pollinators like bees and butterflies. But if you have pets at home, you may wonder—is yarrow safe for cats and dogs?
In this article, we will take a close look at whether yarrow is toxic to pets, what symptoms to watch for, and how you can create a garden that’s safe for your furry friends.
What Is Yarrow?
Basic Facts About Yarrow
Yarrow (Achillea millefolium) is a flowering plant that grows in many parts of the world. It belongs to the Asteraceae family, which also includes daisies and sunflowers. Yarrow is a hardy perennial, meaning it comes back every year.
It has fern-like leaves and flat-topped clusters of tiny flowers. These flowers can be white, yellow, pink, red, or purple depending on the variety. Yarrow usually blooms in summer and continues into early fall.
Why Gardeners Love Yarrow
Here are a few reasons yarrow is so popular in gardens:
- It attracts butterflies and bees.
- It thrives in poor soil and needs little water.
- It helps prevent soil erosion.
- It adds color and texture to flower beds.
- It can be used in dried flower arrangements.
Yarrow is also used in traditional herbal medicine. Some people make tea or salves from its leaves and flowers. But while it may be helpful for humans, it’s a different story for pets.
Is Yarrow Toxic To Cats And Dogs?
