Plant ID please (possibly/probably a tomatillo!)

Nightshade family...maybe a ground cherry of some sort?

sure looks like a Physalis! not a species i’m familiar with, though.

Pending production of fruit, I'd call it tomatillo.

Looks just like my tomatillos but you should know fairly soon when fruit starts setting. Nice healthy plant though.

Thanks everyone!

It would be wonderful if it's a tomatillo

At first though I was perplexed how one could show up there as we have not grown them for years and never at this place?

This is how it might have happened....
Our son gave us some beautiful tomatillas over the summer...my husband made salsa verde.
All of our non soapy water at the kitchen sink is saved and poured out the window into a tub and from there I bucket out to water plants in that location...We think there must have been fresh seeds in the water when I poured the last of the tub on the edge of that bed

Fingers crossed and all for fruit before we get a frost!

i have had similar things happen with tomatillos-- i grow them every 5 years or so, since nobody eats them but me and i end up with gluts of tomatillos. during the intervening years (all of them) there are still tomatillos that come up. they seem to be really tenacious about coming back!
fingers crossed, hope it works!

Thanks Tereza!

I try to watch for volunteers and find them as exciting as anything I've planted....it's good to know tomatillos are that prolific.

I've added a picture of the area...am still surprised I didn't notice it until very recently but then I've been distracted by my pet spider that is right there within a foot of the nightshade.

The hose from the faucet goes to our washing mch on the back porch (which is strung with clothesline) and the black tub is where the kitchen water goes (photo from open window)...sometimes filling twice a day.

I've called it my shade garden because it's somewhat protected from afternoon heat but really it still gets a lot of sun.
To the right are tubs of moringa and dahlias and thyme and on the left with the nightshade on the edge are hazelnuts, elderflowers, coralbells, a hosta, feverfew, orris root iris, daylilies and other iris, blue salvia, bugle weed and some rose cuttings...a blueberry...and a lemon balm...getting crowded.

I tried to circle the tomatillo and the spider egg case but couldn't get it too work.  Got it!
Tomatillo circled on the right, spider egg case on the left.

Not so sure it's a tomatilla anymore?
Sprawling and blooming but lanterns are still smalll and no fruit inside?
It's from the bottom of the photo to the top...not bushy at all.
I like it with my blue salvia though

Tomatillos require cross pollination, at least two separate plants. One without outside pollen does that, it makes the little lanterns, but there's no fruit inside.

Yes, I also suspect it to be a tomatillo. While it may have come from your water, it may have also been planted by birds. They’re very effective tomatillo planters.

Your volunteer likely just needs a friend to grow fruit. And no worries about gender mismatch, since tomatillos are hermaphrodite. If you can find it a buddy, you’ll get fruit on both!

Do you still have many pollinators around? You might try sacrificing 1 flower to push against several other blooms and see if that helps?

That said, I have found tomatillos to have a mind of their own and tend *not* to make fruit until you think it's too cold for them to bother trying. Then all of a sudden, I have a bunch. However, was it the temperature, or was it that the right pollinator just happened to come by one day... Sometimes, I never know, I just observe and make educated or uneducated guesses!
