Grows like crazy, even faster after being cut back! It's over two feet deep on the walls in places. Hubby spends a lot of time he'd rather spend doing other stuff just keeping it from covering the windows and lifting roofing!
Pluses are that it insulates the house, provides pollens for beneficial insects in autumn at a time when there's not much else available, and we have loads of birds nesting in it. Also covers the ground and forms dense mats, useful for places you don't want erosion control. But it's impossible to contain once you have it, will weaken earthen houses, and will get behind any sort of sheathing and lift it.
I've sworn never to have a place with English ivy on it again!
