Have you seen this invasive species? You've probably smelled it.
Bradford pear trees are native to China and Vietnam, having been introduced to the U.S. in the 1960s by the United States Department of Agriculture . The introduction was positive at first, as the trees were both
and able to grow in different climates and different soil varieties."We thought, 'Gee, this is a panacea,'", professor of horticulture at the University of Georgia, told NPR."You can stick it into any planting space in an urban situation, in concrete-heavy soils, clay soils, limestoney soils, acid soils, and it's gonna grow."
However, when Bradford pears started sprouting up all over, crowding out other plants while providing limited food to insects, and simply falling apart due to weak branches, experts learned that the trees were creating a larger problem. Issues are so severe that some U.S. states have banned the sale and cultivation of Bradford pear trees. According to, new sales of the tree will be banned in South Carolina as of Oct. 1, 2024. Pennsylvania enacted a ban on both sale and cultivation, effective Feb. 2024. Nurseries and landscapers in Ohio must phase out the sale of these trees over the next five years, as Bradford pears were placed on the invasive species list in Jan. 2018.
