Hydrangea – Toxic Plant of the Week

Hydrangea
Welcome to another Monday and a new member in the a-z of plants your horse can’t eat. Today’s plant is a true colorful beauty, the Hydrangea may be lovely, but don’t even think about picking a bouquet for your horse!

A Little About Hydrangea

Hortensia is more commonly called Hydrangea. This is a deciduous shrub which can grow to 6 feet tall. Leaves alternate and can be lobed or broad and round. Flowers grow in clusters, have four petals and are white/pink/mauve/blue/purple/cream.

How Dangerous Is It?

This plant is unpalatable to equines and generally only a threat during drought conditions. Often used in ornamental planting and gardens, this is a commonly found plant and worth noting. Hydrangea contains hydrangin, which is a cyanogenic glycoside and toxic when consumed in large quantities.

The bark, leaves, flowers and buds of this plant are toxic and can be fatal (in high doses) to equines.
