Quick Answer
To identify poisonous plants, carry a field guide, observe distinctive features, and consult a botanical expert if necessary. Recognizable characteristics include leaf patterns, thorns, and colors. Be cautious of unidentifiable plants.
Knowing the Enemy: Familiarize with Lookalike Plants
Familiarize yourself with plants that have poisonous lookalikes. For instance, the edible jack-in-the-pulpit (Arisaema triphyllum) resembles the deadly poisonous lords-and-ladies (Arum maculatum). Also, be aware of poisonous plants that resemble harmless ones, such as deadly hemlock (Conium maculatum) and its edible cousin, Queen Anne’s lace (Ammi majus). Research to recognize these doppelgangers.
Plant Identification Tools
Carry a reliable field guide that includes detailed descriptions and photographs of poisonous plants. Some notable field guides include “Newcomb’s Wildflower Guide” and “Wildflowers of North America.” In addition to field guides, take note of plant features, such as leaf arrangement, flower color, and bark texture. This information can be used to narrow down a plant’s identity. For instance, if a plant has shiny, dark green leaves with wavy edges, it may be a poison ivy lookalike (Toxicodendron radicans). Consult a botanical expert if you’re unsure.
Safety Precautions
In areas with poisonous plants, wear long sleeves, pants, and gloves to minimize skin exposure. Avoid touching plants with your bare hands, and refrain from eating wild greens or berries without proper identification. If you suspect poisoning, seek medical attention immediately. In the event of skin exposure, wash the affected area with soap and water and seek medical attention if irritation persists.
