[Herbalist] invasive climbing ivy

[robert leonard]

Hi, folks:  I have just managed to kill an incredibly fast growing, woody,
strong, well rooted ivy with an ivy killer that I purchased at Agway.  I
tried pulling it up over the last year, but it came back like the plant that
ate Chicago.  I have had little luck identifying it; I have looked at a lot
of pictures of invasive ivies online, but no go.  But I will describe it
with the hope of identification:  (The ones in my back yard are dead, but I
found some others growing a few blocks away from my house, in Carlisle, PA,
which is about 18 miles east of Harrisburg, pA)

Green long heart shaped leaves, approximately 5" long, 3" wide.  It is a
tough, woody vine, and is now (Late July) growing clusters of green berries.
Has tendrils that are snaky and grow up in the air when they run out of
something to attach themselves to.  It grows along the ground, has attached
it self to a wood privacy fence, a concrete block wall, to almost any
surface.  It attaches itself with a great grip.  It grew into my large,
unlit metal shed and absolutely thrived in it.  The shed is hot and receives
no light.  I was surprised late last summer to find it wrapped around
everything in the shed.  Last February, I took a mattock out next to the
shed where there were literally dozens of cable like ivy shoots growing
parallel along the ground, and slipped the mattock underneath the stems and
with all my strength over the next hour, dragged as much as I could from in
and along the ground.  I filled 6 huge garbage bags with the vines, but by
June of this year It began going hog wild again.  It is not kudzu.  Or not
the kind I've seen a lot of pictures of.  The ivy killer i used did the job
for now.  It's been about five weeks and I have not seen it spreading
anywhere else.

If anyone can identify it, please let me know.  Or is there a source online
with PICTURES?

Thanks!

Bob
