Thank you, Jay! That's what google lens came up with, but it wasnt in any of the seed mixes I planted, so I was thinking there might be something that looked similar. But I googled all of the flowers in the mixes and none of them seem like they could be this plant. Thanks for the warning about the seeds! I am trying to keep some other things in check and I dont want another 'situation'. Is it possible that a goldfinch deposited them? I have a finch sock right by the flower bed. I've never seen this anywhere else in the yard.

Yes terri it's definately possible that a goldfinch did it. They are smart and probably plant seeds on purpose. They nip on my Silphium flowers so the the remaining seeds will be a bigger snack. It's also possible the seed was laying dormant in the soil, and it germinated once it was exposed to the surface? They are native. Their foliage can vary, depending on conditions. It can look sleek and it can look ratty. Right now I have 1 vollunteer that only gets a few hours of direct sun, and it's a smaller size that I like, but it wont put out as many blooms as those grown in more sun. They vollunteer regularly, so I consider them somewhat expendable if rhey are blocking the sun from something nicer. I prefer growing a few other perennial Oenothera species like O. fruticosa, O. pilosella, and O. macrophylla. Missouri Primrose, Oenothera macrophylla is a beautiful plant for poor, dry soil. The leaves and stems feel like a succulent, and it grows prostrate across the ground and it has an enormous light lemon yellow flower that unfurls in the evening. It looks spectacular grown with Prickly Pears, Red Hot Pokers, Agave, Rattlesnake Master, Purple Prairie Clover and Lead Plant, etc.

The Oenothera is very possible. But I'd keep an extremely lusty and well-fed Hesperis matronalis in mind until flowers prove otherwise.

Does Hesperis push out multiple stems like this floral? I grew Hesperis years ago and I never had a 1st year plant that was anywhere near this large size.

Not sure if it will help confirm, bit posting a few more pics. The main stalk/stem is soft and fuzzy, as are the leaves. Will post more pics once they flower. Thank you both!

And the height of the tallest one is about 4 feet.

Jay, my apologies. Evening primrose is actually on one of my seed mixes. I can't wait to see them in bloom!

Terri, This is the smaller sized Evening Primrose that is in part shade. I read that Oenothera biennis seeds can stay viable for 70 years.

Update, almost 2 years later... this native was prolific in my little wildflower garden (see pic in bloom), so I thought it best to harvest as many seeds as I could, to keep them from getting out of control. My farmer neighbor planted them in a buffer strip and I have to ask how they are doing. If they are blooming this year, I'll post pics. Sooooooo many seeds...!
