A customer brought this to me at market for identification. Someone sold it to her as an herb and it has spread all over. No one at market could identify. Any ideas? Sorry, it was very breezy so hard to get a good photo.

I don't recognize it. Does it have an aromatic leaf?

Maybe Pyrethrum parthenium

Slightly. A couple of people tasted it and still didn't recognize it.

Maybe...

It looks like 'cutting leaf celery'. I imagine if someone tasted it they would have recognized the taste, so probably not correct.

I thought about feverfew as well. Just not sure. At any rate, they told her to pull it, it's a WEED because it has spread everywhere.

spread yourself easily, but easily removed.
It is not a persistent weed and . Nice flowers.

My garden

maybe tansy? Tansy has a bright yellow button flower. Does yours have any type of flower or just spreading? I have Mugwort which looks similar, but I don't' think you have that. It smells like chrysanthemums and spreads everywhere. A real nasty weed.

I thought of tansy but I have tansy and it's a bit different. I'll ask her next Saturday at market if it's any of the above if she can remember. I also asked her to watch for flowers.

Sounds like mugwort... Especially the "spread all over" part...

I believe you've hit the nail on the head! Thanks.

I am confused. What did you identify this as? I really don't think it is mugwort. Have you smelled this plant, does it smell like chrysanthemums? seen how it grows? is it a fibrous rhizome that is literally un-pullable, it breaks off right where you pull it? The foliage for mugwort is very soft, as the season progresses it gets a harder central stem that becomes woody.

Oh gosh, hope it's not mugwort. I fought that stuff for years at my moms, but it sure does resemble it.

It doesn't look like mugwort to me either. If it was mugwort the leaves should be silver/white on the undersides but it doesn't look like they are.

Somehow it reminds me of Chinese parsley or most people call Cilantro.

Also rather like chervil. Difficult one!

I'm so not good at comparing photo's for identification. Do you know what the roots looked like? My first thought was maybe Wild Carrot Queen Anne's Lace (Daucus carota) which grows all over the U.S. and many think of it as a weed.

To me it looks like all the mugwort photos I saw. I don't remember the odor exactly, but it was mild. So I guess that would also rule out mugwort? Would a nursery sell mugwort as an herb?

I think we can rule out cilantro, tansey, wild carrot. I am familiar with those. I will have to ask her more questions on Saturday.
