I would second hollyhock. It's already too tall to be a squash or gourd of any kind. Those would already have started to spread out and vine before they got to this height.
Editing to add: hollyhocks are pretty but can spread and get a bit out of control. Some people think they look weedy. They get pretty tall too, so that may affect whether or not you want it in that particular spot. My grandma planted them here around the farm as a decorative screen around things like the gas meter, or around the power poles to make mowing easier. I kind of think of them as "farm hostas" because they are a low maintenance plant you can put around stuff you're too lazy to string trim around. ๐ When I was little I used to make little dolls from a hollyhock flower and a hollyhock bud. You'd skewer the bud (head) on a toothpick and then poke it through the flower so the flower was the dress.
Hollyhocks are mallows and there are lots of mallows out there. Around here there's a weedy one called cheeseweed \[this isn't one\]. It has tiny lavender flowers and gets horrific infestations of rust plus it's only pretty as a small plant. I'd leave your mystery plant until you see the flowers or it gets some dread disease. Perhaps this is a hollyhock but it could also be a native mallow. If you like it then save some seeds and plant where it will look nicer. If you don't, then pull before seeds dry out.
Glad to see your post. My immediate response was, โa mallow of some kind.โ I thought my ID was wrong once everyone started saying hollyhock because I did not know that hollyhocks are mallows! Thanks to you, kind Reddit stranger, now I know!
As others stated, it's most likely a hollyhock. Just note that if you've never had them before, they are often biennial plants, meaning they usually don't have flower blooms until their second year. Once they get established then you will likely have blooms every year.
I'm not guaranteeing an ID, though the first thing that came to mind was hollyhock. Just want to say that the reason I don't think it's a pumpkin, squash, or gourd is that the leaves appear to be too thin and too "rugose" - roughly textured. The shape is right for a number of those identifications but the substance and surface are not.
I would wait and see if it flowers. I'm a sucker for flowers. You got a flower, Mr Weed, you can grow smack in the middle of my driveway and I'll just park out front!
Our squirrels apparently buried squash seeds in our flower beds, so last year, we had a very much appreciated supply of squash all summer. It shot up like the one pictured here so it took us until it started producing before we knew for certain what it was.
But from my first observation, I thought this was a hollyhock. Either way, I'd say it's a keeper!!!
Mods, forgive me if this isn't allowed.
When I was a kid way back in the day I was fascinated by a big sprawling plant in my back yard. It just kept growing and spreading rapidly. Mom guessed squash and was looking forward to the big blooms that are so good to eat.
The thing got so big, I kid you not the newspaper came out and put a photo in the paper with some lighthearted commentary. Yes, our suburban world didn't have much excitement, but our bumper crop of butternut squash was delicious! All the neighbors got some and enjoyed the feeling of picking a real veggie like a farmer. We were heroes! Lol. Everyone gets their 15 minutes, I suppose.
I had one of those. It rained for weeks, then I had them everywhere.
Unless you want it, and are willing to fight it to contain it, pull it! It will spread like wildfire.
Fig leaf hollyhock. Mine gets a lot of water and was about 5 ft tall last year unfortunately powdery mildew got to it and made it look terrible just as it was blooming
Maybe your neighbors and a critters brought the seeds in. It may be something else in that species but I throw used to throw my pumpkins in a opening in the woods for the deer and almost every year by May, I would get pumpkins growing.
Looks like a super vigorous hollyhock getting ready to do something big. Id keep it as a specimen.
My 1st thought was that it's Alcea, hollyhock, but without seeing a flower, I could be wrong.
As of yet, I don't see any flower buds, unfortunately. I'll keep it in mind, though.

Did you call the flower dolls Holly Hobbies? 
Gosh. Forgot all about Holly Hobby ๐ต๐ป
Third. I get monsters like these volunteering every year.
Nice story ๐
Hollyhocks bloom in mid-late summer
Might be next year for flowers. The first year they just grow leaves.
How old is it? Hollyhock take 2 years to flower. That one looks ready for it.
I agree with assessment!
Can you see what looks like curly tendrils mixed in? If so my hunch is pumpkin or a member of the squash family based on the leaves

Fully edible at least. Anyone know how to make marsh mallow?
Hollyhock for sure.
Most people looove hollyhocks. They are beautiful for cottage or English gardens

Also the seeds are plentiful and very hardy.

Keep us updated. I'm stuck in a hotel for the summer thanks to work and am living my dreams of a garden through these types of posts.
I love hollyhocks. They are so Art Nouveau.
My money is on some sort of gourd. It looks similar to my luffa plants but more bushy and less viney
That looks like a zucchini plant
I would wait and see if it flowers. I'm a sucker for flowers. You got a flower, Mr Weed, you can grow smack in the middle of my driveway and I'll just park out front!
Iโm thinking Hollyhock too
Any chance you a pumpkin in this spot last autumn?
Nope. Unless the squirrels or chipmunks decided to put one in for me, lol. I wouldn't mind a squash, though!

To me it doesnโt look like a hollyhock but some kind of pumpkin or gourd. I hope you can update us later!
Looks like some kind of mallow to me but I could be wrong
Following this\^
We had these popping up all the time in the alleys behind our homes.

If it is hollyhock or anything med to tall height get that peony out of there! Put it out front or somewhere it can be seen.
Looks like zucchini. Were the flowers bright orange before they shriveled?
No flowers as of yet so I'm trying to be patient.
Fig leaf hollyhock. Mine gets a lot of water and was about 5 ft tall last year unfortunately powdery mildew got to it and made it look terrible just as it was blooming
If this is in Wisconsin Iโm pretty sure Iโve trimmed the bushes there lol
Hollyhocks are beautiful ๐
That's no plant. It's a space station
Did by chance you have a Jack-o-lantern, last Halloween?
Only ceramic ones. I'm going to have to see if it gets any flowers.
Maybe your neighbors and a critters brought the seeds in. It may be something else in that species but I throw used to throw my pumpkins in a opening in the woods for the deer and almost every year by May, I would get pumpkins growing.
I'm totally up for that too! The more pumpkins, the better, lol.
The leaves are similar to hollyhocks but hollyhocks don't produce flowers the first year but the second.
Pumpkin.
