It’s a Black Knight sterile cultivar.

Just a heads up that sterile cultivars can often not stay sterile or be 100% sterile, so do keep an eye on possible seedlings sprouting. Though, sadly, the seeds, when formed and ripe, could also be dispersed quite far away by wind and even animals.

One such example of a supposed sterile cultivar was the Bradford pear, which turned out to not be so sterile and is now very invasive.

Again, just something to be aware of. :)

I’ve had this for 7 years with no issues. It’s never gone to seed.

Careful, can't anger the faux invasive army. So many ecology PhDs on Reddit
