<div>My mind is foggy from highway miles, but I'm pretty sure that I was along the PA turnpike between Philly and Valley Forge this winter when I saw a Miscanthus field that covered a few solid acres, and the plants themselves had then spread out along the highway embankment for at least a mile, probably getting dragged along further with each pass of the mowers and each breathe of wind. It may have been the most horrifying "newish" invasive spread I had ever seen. The field itself was massive and stood out like a hay field ready for harvest. It was dumbfounding. It certainly merits some serious attention.</div><div><br></div><div>Mary </div><div><br></div>

<div>Miscanthus and Pennisetum are both problems in
coastal Delaware but I would add that they spread primarily
from being planted, then the seeds are wind blown. Regarding
Phrag, some areas here have given up on eradication, and are
now concentrating on managing it, if that’s even possible. We
are very prone to flooding, though, so with sea level rise
which we are living, it will be interesting to see it move as
it doesn’t tolerate standing water. </div>

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.

<div>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.
