With their large, eye-catching clusters of blue, pink, or white flowers, these shrubs bring elegance and color to landscapes and indoor spaces alike. But here’s something many plant lovers may not realize — hydrangeas are far more than just pretty decorations. In fact, this beloved flowering plant can pose a serious threat to your feline friends.
