I'm in Toowoomba qld, have a customer who has this creeper, can anyone Id it please. It seems to travel under ground, then sections come up, and it climbs prolifically up other shrubs etc. I just dig it out, when I see it, plus apply round up to other sections, all I do is slow it down really, but by keeping at it, it hasn't smothered any more shrubs, I'd love to eradicate it, but I imagine that's nigh on impossible, anyhow thanks in advance for any advice, cheers john
