Not sure on this one, the leaves looked like a non-weed, so I've left it to grow, it's got small yellow flowers budding... anyone?
Hi Paulina, this is some kind of beggarticks (Bidens), probably either Bidens frondosa (with orange flowers and 5-8 outer involucral bracts) or Bidens vulgata (with pale yellow flowers and 10-16 outer involucral bracts) according to the "illustrated Flora of British Columbia". If the big leavelike bracts below the flower heads are meant by "outer involucral bracts" then I might prefer Bidens frondosa, but I am not sure whether I can see all of them and which color the flowers are going to have. Robert.
OMG... English please? (Sorry, I'm not that advanced in the garden language yet)... The flower buds that are coming out are very tiny yellow, which makes me think it's a weed... I'll try to get some more pics when the buds open up. Thanx though!
