List of Poisonous Plants in Florida

    • Florida is one of America's most populous states and also one of its most popular travel destinations. Florida is prized for its natural beauty and world-class beaches. Florida is home to several different poisonous plants. With proper knowledge of these plants, you can avoid being subject to their toxic nature.

    Arrowhead Plant and Other Similar Toxic Plants

    • Characterized by its arrowhead-shaped leaves, the arrowhead plant is poisonous when ingested. As soon as the plant is chewed, burning in the throat, lips and mouth occur. Vomiting is a major side effect when swallowed. Other plants with similar side effects if ingested include caladium, philodendron, peace lily, pothos and dieffenbachia. These plants are often found as additions to gardens; keep children away as they will be unaware of the plant's poisonous nature.

    Oleander, Lilly of the Valley, Foxglove

    • The oleander is poisonous in all parts if ingested. Though not dangerous to touch, this plant causes severe symptoms if eaten. Symptoms include vomiting, diarrhea, dizziness, confusion, headaches and, in rare cases, even death. If it is used as a garden plant, keep away from children. Animals have a tendency to keep away from the plant; pets usually are safe even if near the plant. Lilies of the valley and foxgloves are two other plants that have similar side effects if ingested. Neither of these plants is poisonous to the touch.

    Angel's Trumpet

    • The leaves and seeds of angel's trumpet contain a light poison. Mild symptoms if ingested include increased heart rate, confusion, flushing, dilated pupils, fever, muscle weakness and constipation.

    Castor Beans and Common Lantana

    • These two plants are fruiting plants; if the berries are digested, severe symptoms can occur. Eating the berries of the lantana can cause shallow breathing, dizziness and blurry vision. Eating castor beans can induce bloody vomiting, drowsiness and, in rare cases, death from kidney or liver damage. Castor beans contain traces of ricin, a deadly poison. These plants should not be planted or grown in a garden near pets or children.

    Glory Lily

    • Glory lily is an extremely poisonous native plant to Florida. Digesting any part of this plant can cause death from multiorgan failure. The glory lily, beautiful but deadly, should not be grown in an area where children play or go.


    • Poinsettia, a common plant associated with the winter holiday season, is a mildly poisonous native plant of Florida. The milky sap from broken stem or leaves can cause irritation on the skin. If digested, vomiting can occur. Eating the berries of the plant can lead to dehydration.

    Poison Ivy

    • Poison ivy is a common, poisonous plant native throughout North America, including Florida. Touching the leaves or the oil from the plant can cause sever itching and blisters.
