Safe & Unsafe Plants

Plant List

NOTE: It’s the dose that makes the poison. Some plants one bite can be harmful, other plants may take eating the entire plant. The same plant in Florida may be less harmful in Washington, or more harmful. Call 1-800-222-1222 if you have questions about plant toxicity.

Lists of  safe vs unsafe plants are never complete and can be hard to understand. Some toxic planbts look like nontoxic plants when trying to name it by a photograph. It is best when buying a plant to check with the store clerk. For plants you currently have, bring them or clippings to your local garden store.
