While most of us are familiar with common poisonous plants that cause dermatitis (skin irritations) such as poison ivy or poison oak, we fail to recognize common ornamental plants in the landscape that may cause internal poisoning when ingested. Although most adults would not intentionally eat the leaves or fruit of ornamental plants in the landscape, young children or pets sometimes do. The purpose of this publication is to familiarize you with some of the common landscape plants known to have poisonous properties when ingested. You may be surprised to learn just how many of our common plants, such as azaleas, hydrangeas, boxwood and English ivy, are known to have poisonous properties.
