That my friend is - multi-flora rose... and I was (we were) dead center in the middle of a 20 acre patch.. You come out of there you look like you've been sacking cats. Interesting part is it was native to Japan and the *government* brought it here in 1866 (actually some was brought here privately as early as the late 1700s for ornamentals). It was first planted to make a "living fence". Of course (as so often happens - It's not nice to fool (with) Mother Nature) it is highly invasive.. it got so bad here in the 60s and 70s you literally could not walk through many timbers without a set of shears to cut a path... And until about 1970 you could still buy plants from the DNR.
Enter (once again) the government - In the 80s they introduced some mites and diseases they had isolated through study. Not sure which - but one of the two went through ours like shit through a tin horn.. "Killed" virtually *all* of it.. It still comes back - but as soon as it get anything more than a few scattered plants - bug or sick wipes it out again..
Now - let me tell you about Tatarian Honeysuckle, another gift from the government.
