    Hey folks! I'm working on a greening project in Montreal, Quebec; and I was wondering if it's possible to grow vines (virginia creepers & boston ivy), from the ROOF, DOWNWARDS. That is, they would be planted in a very large container on a rooftop and expected to grow down the wall, instead of planted at the base of a building and grow upwards.

    I need to know if they can be trained to grow downwards, attaching to the stone in the same way as when they work up a wall. The reason I need to know is because we're interested in greening the walls of some buildings but can't get excavation permits for the base of the edifices due to wires, gas lines, etc etc...

    Anyone have any experience with this? Any information you can offer will help a lot. There is nothing about this kind of thing being done that I can find on the web.

    Thanks!

    Interesting question. In Seattle the ivy grows down the walls of the freeway. It hangs down at least 10 metres in some areas. Hedera helix is a rampant invasive in the region. May not be as vigorous in Montreal.

    Describe the stone wall. Ivy would attach itself more easily if there was a certain amount of roughness present. And: I have heard that, over time, ivy has a deleterious effect on brick walls. Would this also be true for stone?

    Take a look at this:

    They would drape, probably not becoming attached. This might be better than having them stick to the walls - as long as there wasn't a problem with them blowing about and becoming tangled during high winds.
