Did you sow Sorrel?

Looks like Rumex crispus

Thanks for the reply! No, I did not plant sorrel. I just went through all of my seeds to make sure even though I didn't think I had that.

It does looks like some sort of dock/Rumex

It is considered an edible plant.

If you did't plant Sorrel I'd go with the curly dock id. While edible they are not very palatable imo.

Thanks everyone! It must have came either from the potting mix or possibly a seed packet because it's nothing I've ever seen in my yard. I'm going to pull it out because it doesn't sound like something I want around.

Have you tried Pl@ntNet or Plant.Id? Both are great apps when you aren't sure what's growing in your yard or if you come across something interesting when outdoors.

Were the other things purchased transplants or started from seed?

Stray weeds can get into nursery plants, IMPE.

@Sarah Marshall, Thank you! Those look like very helpful sites.

@carolb_w_fl_coastal_9/10, All the plants were planted by seeds in this plant tower, but I agree that purchased plants do come with weeds sometimes. That's why this was such a mystery to me.

@Jay 6a Chicago, that looks like what it is, even though the sorrel that @
floral_uk z.8/9 SW UK suggested looks to be similar. Thanks to both!

" Those look like very helpful sites. "

Not any more helpful (or accurate ) than The Name That Plant forum here on Houzz/GardenWeb!!!

FWIW, sometimes stray seeds show up in purchased packets - and weed seeds can sometimes lay dormant for years before sprouting as well.

Sorrel would look similar since it and Curly Dock are both species of Rumex. I suggested Sorrel because, although it looks more like Dock, Sorrel is a cultivated edible herb and you said that's what you sowed.

I planted four different herbs including thyme, in the spot where the thyme was planted this plant showed up and I have no idea what it is. Any ideas?

Did you sow any mustards? And where on the planet is this growing?

For future reference it is best to start a new thread of your own if you have a new question.

why did you not start your own post... why piggyback on an old post..unless you are the same OP

many.. if not most.. seed is air borne.. one way or another... sterilize your potting material.. before you planting it.. to insure it is sterile.. this will help you avoid rogue seedlings.. then plant the seed in pattern.. so anything outside the pattern.. is a weed ....

The above information is dubious. Many seeds are not airborne and sterilising potting media for outdoor growing is not going to stop weed seeds from arriving.

please see new post

good to now im not going insane.. thinking i saw and answered things yesterday...

link to your own new post... ill do it in the other post...

The poster has started a new post with two photos. The additional picture has several plants in it which give a scale for the mystery plant. I believe the foliage is too large for Capsella bursa-pastoris. https://www.houzz.com/discussions/6420925/mystery-herb-plant

An additional tip: put something in the photo to give a scale or include measurements.

We need a location to see what Brassicaceae and Asteraceae are growing in the area.
