For all you super plant sleuths out there, is this ragweed? Or something more desirable? I'm trying to decide whether to pull this or let it be!

Looks like it may very well be ragweed. If you don't remember something desirable being there last year, I'd yank it.

I've been pulling up Ragweed seedlings along the roadside as I walk the dogs and to my eyes yours looks different. Can you let it grow just for a little while longer? If I'm wrong there will still be enough time to pull them before they get ugly and mean.

Feverfew (Tanacetum parthenium)
The thread "Weed or an herb for ID" in Plant ID forum

Pyrethrum parthenium is synonym of Tancetum parthenium according to The Plant List..

I agree, if that is the plant, the flowers are very pretty and it has medicinal properties, I love the smell of the whole plant.

thanks all. I believe someone gave me some feverfew at some point so could very well be it! And from the links to prior conversations, looks like it could also be mugwort. Well, I should probably pull it--feverfew, mugwort, ragweed--either way, I probably don't want this plant spreading everywhere.

Trust me, that is ragweed. I have been pulling it for about 4 years! Don't let it go to see what it does, you will be forever getting rid of it. The stuff spreads like wildfire and not just by seed but by runner and rhizome. Wear gloves if you think you are allergic!
Good luck!!

Kind of looks like ragweed to me also.

Doesn't look like the ragweed around here.

Ambrosia has more pointed leaves, but for young plants may not be as strongly.

I think it is False Ragweed; http://uvalde.tamu.edu/herbari...

thanks, Josephine! I think that is similar to what Stefan and Myriam were suggesting--feverfew? It does look like it.

You'll know when it will flourish

I think my allergies would be too great either way to let it get to that point! Think I will need to yank it soon...

There is more than one variety of Ragweed (Ambrosia) as a matter of fact there are at least 17 that I know of. Good Luck

BONAP show 28.

thanks, Jay. With a name like 'Ambrosia' you'd think it would be a more desirable plant!!

You are right, I wonder who named it?

Probably named by Carolus Linnaeus; seems like he named lots of stuff.

You are correct, it was names be Linnaeus.
