"Poisonous" does not mean deadly. Some manifestations of toxicity are subtle. The dose, as always, determines if a plant is safe source of nutrients or a toxic hazard.

If you receive a message saying "no rows found", it means that the plant you are searching for is not in our database. Otherwise, you may click on the scientific name to view the image(s).
