This past summer (2016), we've experienced drought conditions in Ottawa, Ontario Canada, yet this vine has done very well on nature's short rations. I first noticed it growing in a wild area of my neighbourhood a couple of autumns ago & since that time it has doubled it's area of growth, though doesn't appear to be invasive of the untended spot that it's living in.
