An invasive has overtaken my garden—what is it and how can I get rid of it?

I share a backyard in East Vancouver with three other neighbours. The garden is nutrient rich and yields a wealth of both veggies and weedies.  After a successful year of planting we discovered that one of these weeds is actually an invasive species.

This year, my fellow gardeners and I took a break over the winter and arrived back to discover the garden was indeed filled with stuff. Despite our plucking, pulling and picking the plant keeps coming back. I’m hoping GardenWise readers can tell me: what is this invasive intruder and how can we ditch it?
