Any idea what this weed is? I think the flowers are pretty but if it is invasive I'll pull them all up. The plants are about 2 ft tall and just started blooming in September.
Thumb of 2014-09-15/bxncbx/3be132. Here is a close-up of the tiny flowers.

Ageratina altissima, native to your area (not a weed).
