Arizona carries many species of toxic plants, flowers, and trees. However, many homeowners may not realize they’ve picked a poisonous tree without the help of their local landscaper. Learn about the most common trees in Arizona that are also poisonous to humans and animals.
Chinaberry Tree
The chinaberry tree can reach heights from 20 to 150 feet, but extreme heights only occur under special circumstances. It flowers with small, fragrant petals that grow in clusters. The chinaberry tree produces drupe fruit that appears light yellow and grows to the size and shape of a marble. The fruit and leaves are highly poisonous to humans, especially when consumed in large quantities.
Eucalyptus Tree
There are hundreds of species of eucalyptus, and they can all grow anywhere from 10 to 200 feet in height. Different species have different leave shapes, but they all have a distinct fragrance that makes the leaves very popular in oils and medicinal use. The issue of eucalyptus toxicity can be complicated. Though eucalyptus has been found to have healing properties, it can be poisonous when ingested in high quantities.
Oleander Tree
Oleander trees grow from about six to 20 feet in height. They produce clustering flowers that appear white, pink, and red in color. Some insects—such as Polka-Dot Wasp Moth caterpillars—can eat oleander leaves without dying or becoming sick. However, every part of the oleander tree can be toxic to humans and animals. Oleander leaves and flowers should never be ingested, and the bark should never be burned or used for firewood.
Texas Mountain Laurel Tree
Texas mountain laurel trees can grow up to 25 feet high and produce dark green leaves and violet-blue clustering flowers. In addition, these trees also produce seed pods that can grow up to 8 inches long. The seeds and leaves produce a toxic agent known as cytisine.
