4 foot tall plant in Eastern MA

A bunch of these seem to have exploded out of nowhere in sunny spots in my beds. None of them has flowered yet. I'd like to verify they're not something I seeded before I rip them out. Any ideas?

Having just posted photos of the same plant last week, I concur with the experts here. Bidens. Do not hesitate to rip it out. If it blooms and goes to seed, you, your family, your pets, your guests, your neighbors and any local wildlife will be wearing the devilish little seeds for months!

Ah but it is the host plant for several butterflies such as the dainty sulphur butterfly. Also a good nectar plant for butterflies.

Let it live and then just cut off the flowers before they go to seed.
