grows like crazy..almost anywhere soil is, even through small cracks in walkways. It can get very large too.

I am in Southern California.

I tried to link an additional pic below

Thanks.

It's in the aster family.
It's an annual which, if left in place will flower and set seed.
The remedy: Remove -- pull it out -- and put in garbage.

A key strategy to limit weeds: Never let them set seed.

Thanks for the info. It's amazing, they even grow through cracks in the walkway into big plants. Can you take a look at the other weed I posted?

Compare it with Conyza canadensis, a widespread weed in the Americas and now also in Europe.
