I don't think I've seen this type of tree before...or if I had, it definitely wasn't in a form like this. The trunks (and some branches) are twisted, the sides of the leaves curl inward, and the fruit (or flowers? I can't tell...) have a very pointed, geometric look to them. Any help you can offer would be appreciated greatly. I'm in Blair, NE, on the line in between USDA zones 4b and 5a.
Ok, that's what other people have said as well. That's as specific as I need to be anyway. Thanks for your help.
