Ohio was the first state in the country in 2023 to ban the sale of Callery pear trees, an ornamental that sprouts white flowers in the spring. The trees, which include Bradford pears, for years were a popular choice for landscapers and nurseries.
The pear trees started growing wild in forests and open spaces across the Midwest. But when a sterile variety was crossed with other varieties to make them more hardy, they began taking over forests from Michigan to Georgia.
The trees in 2018 were placed on Ohio's invasive species list, starting the clock for landscapers, growers and nurseries to replace their inventories. South Carolina and Pennsylvania have also passed bans that will take effect soon.
