Most people call this Canada Thistle, but Creeping Thistle is the more accurate name, as this is an introduced plant from Europe. Was lucky to catch a plant with a flower still on it, as most of the ones I see have gone to seed now. This is an invasive plant that has taken over vast areas all over the city, preventing our wonderful native wildflowers from growing. Has become a real problem that needs to be dealt with - somehow!
