Just purchased and planted a variety of trees and shrubs for our back yard.
One is an Oleander plant. I bought it because it will grow big and the
flowers are awesome. Should I be concerned about the toxicity of the plant?
I keep reading that they are poisonous.

We have a 9 month old son and a dog. My concern is that they will
accidentally touch or eat some of the plant and get sick.

Thanks!
