Bradford pears are a type of Callery pear that when planted years ago were considered sterile plants. Bradford pears develop bad branch angles that eventually caused trees to break apart. So newer types of Callery pears were put into landscapes and they began to pollinate each other and now what was once a sterile plant has fruit that is viable and has the potential to spread. The Midwest Invasive Plant Network does not have it listed as invasive in Michigan. In Illinois it is on the "General invasive plant list". Indiana give it a "High Invasive Rank", Ohio has it going onto the Restrictive Invasive Plant List in 2023.
