They’re invasive, they outcompete native trees, and they have many negative attributes. The wild descendants are particularly bad because they have thorns and grow in dense hard to remove thickets.
They are also terribly brittle. Every single time there is a storm in my neighborhood, at least one person has a massive Bradford Pear split in half in their front yard (if we're lucky - if not, it's out in the road.) Builders plant them because they grow quickly, and, of course, they don't have to deal with the problems a few years down the road.
I had 3 in my yard. I never thought twice about them until one split down the middle & destroyed my carport 3 years ago. I cut the rest of that one down & the one next to it that could fall on my house. A neighbor had one split last summer & blocked the road. The wood from these trees are dense and heavy. I never walk under them anymore due to how quickly they just fall down.
