Excellent observations, Steve! Agree with Mimosa.
<div><br>
</div>
<div>Italian Arum is indeed starting the way Liriope did in the Washington-Baltimore region 20-25 years ago. Both Liriope spp. are now to be found in every urban and suburban park and natural area.</div>
<div><br>
</div>
<div>We might also consider Butterfly Bush as an incipient analog, though yet unproven naturalizer, to Mimosa.</div>

<div dir="auto">One other one that belatedly came to mind is Mimosa. Not that it's one of our biggest issues. But anecdotally, our normal DC-area winters used to get cold enough so that Mimosas seemed to get killed off pretty regularly. Within the last 20
years my sense is that we aren't seeing nearly as much winter kill and more of them are popping up.

<div dir="auto">Off on a tangent, another possible confounder for invasives in general is micro-evolutionary selection pressure. As but one example, I think I see this going on literally under my nose with Italian Arum, where I think selection pressures are
breeding the more aggressive spreaders. There are probably many other and better examples. Garlic Mustard? Lesser Celandine? Etc.</div>
