I'm in 4b so right on it's zone edge. Was considering trying that one next year along with a few others. I planted my first BHWN trees in 2021. A few have their first flowers this spring. Trees aren't really big enough to want to set fruit on so I'll likely pinch them off if they set any. They've been slow growers compared to Northern Whitetail Crabs trees but that's to be expected on the different rootstocks.
