This plant is about 2.5'-3' tall right now, just the one growing right next to a fence, but I've had no luck trying to Google it yet. I have no idea if it ever flowers or has berries, but I'm pretty sure that so far this season it's had neither.

Compare with bidens.
Possibly bidens pilosa.

Probably need a flower to be sure which one you have.

This is interesting.... As much headlines as mrsa is getting, and all the advertisements on TV for all these other discomforts... This might be worth growing for the medicine cabinet.

I agree Bidens. I invited Bidens into my yard because they are good for bees, but... Sighing! ...they are bad for gardeners. I had to fight to eliminate this plant from my yard and it even managed to follow me when I moved to a new place. Keep an eye on it.
My two cents:
If you deadhead and prevent seeds from forming you'll be okay.

It looks like it could be bidens, and seems interesting enough to let it keep growing. It's not bad looking and not full of thorns, so no reason not to let it be and see what flowers will bloom.

As far as hard to get rid of... the opposite fence has a very old trumpet vine that I've been spending my summer so far trying to kill off. I don't think anything can compare to trying to get of that. Hilarious! I read one post from someone trying to kill it that said trumpet vine thinks Round-Up is plant food and I have to agree after my attempts. So in comparison I don't I'll be bothered much by bidens if I ever want it gone.

I've got to agree with Green about not letting seeds form. Those seeds are like treble hooks, and easily relocated in clothing, fur, Etc. They're not easily removed from same. Picture a guy who showed up in sweats to pull weeds...and left looking like a porcupine.

Looks like Bidens species to me also. A few are found in Illinois but here's one for comparison:

There are several that it appears it could be, so that's another reason I want to wait it out and see what flowers it has to ID the specific bidens.

And I've seen pictures of the seeds with those hooks, they do certainly look like they'd easily stick to anyone getting near it. I'll have to decide what to do with it when it reaches that point, whether to just try and avoid it or cut off all the seed pods before they cover me while mowing the grass.

Thanks for all the suggestions. I'm going to carefully watch it for now, mostly because I'm really curious what specific bidens it is after reading about all the possible medicinal values.

@Murky ...

I truly liked the title of your thread. I have a couple of weeds I do keep that are considered invasive because I do like the look of them ... Smiling

So far, they are no more invasive than California poppies or feverfew or a few other wildflowers.

One of them is a plantain. I just like the look of it in contrast with other plants in that bed. Today, a visitor offered to pull "that weed" for me and was surprised when I declined.

I'd rather weed than dust ... the weeds stay gone longer.

Bidens not only are good for the bees but the tender leaves are edible.

Lyn, your plantain is much more photogenic than mine.
