Flower identification

Question

I planted this flower last year and cannot remember what it’s called lol it blooms all up the stem but not at the top and it’s spread like wild fire… any idea what it is actually called?

It is difficult to say, it appears something has self seeded and it looks very much like Horseweed.

You could take a sample to your County Extension Office, as they can help id weeds that are common to your growing zone.

You can also wait for it to flower, as this can help to id the plant.
