Here's 9.5 reasons.

1.) Short lived
2.) Weak wooded - breaks apart for seemingly no reason
3.) Invasive species
4.) Stinky putrid smelling blooms- odor wafts hundreds of feet away
5.) Problematic surface roots are common
6.) Viewed as "McFlora" consumer plant material not used by professionals unless the customer demands it.
7.) Bloom period is short
8.) Fall color is blah
9.) Leaves drop late (second raking)
9.5) Dense shade (& suface roots) makes growing grass underneath very difficult. Probably impossible in your climate.

Thank you very much for youir help!

Strange. I never noticed their putrid smelling blooms. I agree with number 1 and 2. Not worth planting it. There's much better trees to be planted beside this one.

The blooms smell like grungy sneakers, to me. Old, sweaty, dirty, grungy sneakers.

Is there an arborist/city forester anywhere that recommends this tree?

Meanwhile, new Callery Pear cultivars continue to be selected.

As are Japanese Barberry cultivars and Norway Maple cultivars.
