My most aggressive roses wage war on me, all structures and each other. This is all one rose and actually starts a little to the right of the arrow and was growing over a large arbor. It collapsed the arbor (see arrow) and just keeps heading north.

This is another plant of the same variety on another arbor which is leaning badly(see arrow). The huge white Scotch rose on the left is holding its own.. Luckily the big juniper is supporting some of the rose on the right. But if I had to place a bet on which will win I would have to put my money on the rose on the right.. It will eventually collapse the arbor and engulf the white rose AND the juniper and continue on its way.
This unnamed climber below is intent on consuming my chicken house.. Although I try to it from the door and going over the roof, it is a losing battle. It also creeps under the eaves and tries to fill the inside of the chicken house.
But the very very worst is this rose. It is named Darlow's Enigma and is actually sold on the internet. There is a 30' long and 8' tall cedar fence. I unknowingly planted about 10 of these roses along that fence and haven't seen the fence since.. There is no doubt it will collapse the fence and I need to hire someone with a machete (or chain saw) to cut it down and then spray it with round-up. And it is loaded with thorns.

This is a view of the fence on the other side. The rose grows up over the 8' fence, down the other side and into the pasture.
