<p class="MsoNormal">Hi, <o:p></o:p></p>
<p class="MsoNormal">Thanks, Nathan for the feedback. That is interesting to know about Doug Tallamy’s finding. So, if its not as invasive as other tree species like callery pear, are others here in agreement that it can be ignored for the most part? Has anyone
found it to take over areas? I’ve only found it here and there and not dominating areas like callery pears tend to. Or is this an “it depends” conversation?

<p class="MsoNormal">I've struggled with this as well and spent awhile trying to get it right and never got anywhere. If I recall correctly, they hybridize, so it's a real spectrum that's hard to diagnose, and that one feature you mentioned didn't do much
for me. It doesn't help that at least some native nurseries don't even seem to realize this is a thing and it's just "malus spp." On the bright side, according to Tallamy, they are interchangeable as a host plant for caterpillars, at least in species numbers,
if not volume of insects.<o:p></o:p></p>
