[MAIPC] Invasive plants and climate change

[Stephen Hiltner]

I'll chime in with a few observations. The first invasive example of
Miscanthus I saw many years back was in a field outside of Newport, Rhode
Island during my one and only visit there. In NC at turn of the century it
was only invasive on Mount Mitchell and some horticulturist of great
stature, perhaps the one who wrote "the book" on shrubs/trees, said in a
discussion at NC Bot Gardens that only one variety of Miscanthus was
invasive. In recent years I've seen examples of invasion in NJ and PA along
freeways.

Groundsel tree is one to look out for, as it spread from the NC coast up
freeways into the piedmont and has become a serious invasive in the Durham,
NC area, invading grasslands and lining freeway right of ways. Seen a few
incidents in central NJ but not much yet.

Go to Princeton battlefield, and it's hard to imagine porcelainberry
getting any worse--topiary on a massive scale.
