What region does poison ivy grow in?

While most people think of poison ivy as a plant that only grows in the woods, it is actually one of the most common plants and can grow nearly anywhere, including backyards and near sidewalks. It is a versatile plant and thrives in many different forms such as a climbing vine, shrub, and ground covering. Aside from knowing what to look for to identify the plant, it is a good idea to know if you are at risk for poison ivy growing in your area. What region does poison ivy grow in?

Poison ivy thrives in a range of locations. It grows in every American state, except for California, Alaska, and Hawaii. In Canada, it grows in most lower territories. It also grows in parts of Mexico. The reason poison ivy is so widespread is because it is a hearty plant.

While many would falsely assume poison ivy is more prominent in regions with year-round warm weather, it is actually a widespread plant regardless of climate. Poison ivy is an adaptable plant meaning it can survive harsh seasons without dying. While poison ivy is thought of as a spring and summer plant, it is still around in the fall and winter. In the fall the leaves change colors like any other plant to a red, orange, or dark brown hues. As winter approaches, the leaves will fall off, and the green vine may turn brown. While the threat during the seasons of fall and winter is weaker when compared with spring and summer, the oils may still be present so avoid plants year-round to avoid a reaction. The plant’s ability to adapt means it can grow in regions with harsh climate changes, as well as states with milder changes throughout the year.

Poison ivy is not confined to state parks and other wooded areas. Poison ivy can grow in many settings, including backyards, up office building walls, and in between sidewalk cracks. Remember poison ivy is adaptable! Where the elements of successful growth are available, such as sunlight and rain, poison ivy can thrive. Always check your backyard regularly for poison ivy indicators to avoid the painful rash associated with the plant.
