Any ideas on what this is?

Pretty

Judy, I don't know what they are, but they're so pretty I would decorate around them. You could let them reproduce until you have enough for a flower bed, then block them in with a border. Someone on here may come along and give you the name of the plant.

i don't know

It could be a variety of nettle. Your best bet is to get in touch with your local botanical garden or native nursery where you can show them your photos. They should be able to help you identify the species of plant so you will know if you want to keep it in your garden or not. Good luck!

It almost resembles a bird of paradise plant; maybe its within that family... Id take a picture to the local nursery and ask. Dont touch it till ya know what it is though, bc it could be poisonous.

If you live in the lower 48 (most of the US!) it's probably Evening Primrose, Oenothera biennis, a beautiful native plant tha feeds pollinators at a time when many other pollinator-friendly plants are out of bloom. (In my 3-acre garden I can't get enough of that light, clear yellow—so many flowers run toward bright/deep yellow or yellow-orange.) If yours is blooming now, you must be farther south or west that I am, in rural central-western Maryland. I'm impressed and frankly amazed that your foliage is not chewed up by Japanese beetles: Oenothera is Jap. Beetle candy! Here's a link that'll give you a more info.:

This is a type of mullein. Looks like it might be what is called Great Mullein. It’s actually a type of herb. You can google mullein and get more info and pictures of the different varieties to help identify your specific one

Doesn't seem "velvety" enough for Mullein but that was my first guess also.

Evening primrose, Oenothera biennis. Spreads very quickly. Since it's a biennial there will just be basal leaves the first year and flowers the second.

If is like this, it is listed as a flowing weed

Impatiens balsamina

I live in Ohio and have had Evening Primrose pop up in various places in my yard for years. They are night bloomers and only last one night. I find them pretty and fascinating. They are the only plant I know of that you can actually watch the flowers open. If you'd like to watch a slo-mo miracle go out just before dusk and see them begin to slowly open for several minutes. Then suddenly the burst open into all their glory!

Yep, along with a few microclimates on our property and global climate chaos, bloom times and vigor of plants varies widely from one year to the next, let alone from one region of the state to the next. I'm expecting to see my Oenothera start blooming by the end if the month or early Aug. ~ How many of you are Wisconsinites, anyway?! Sorry for your particular area's drought. We've certainly gone through drought other years, but this one has been wet, flooding wet.

Came in a package of mixed flower seeds....pretty yellow flowers, grows +/- 2 ft tall
