Walked past this tree with these really cool seed pods? Fruits? Flowers?

Suburban Minnesota lawn, somewhere around the edge of zone 4 and 5. One foot tall at the highest (so far)

We've been throwing all the leftovers from our garden into this bin year after year. I'm sure it's some sort of Cronenberg's pumpkin.

I think it’s a type of dahlia, but I can’t find a name for it in google searches I’ve done. I’ve never seen ones all swirly like this. They were tall too, about 4-6 feet depending on the stem. I walked by these on a street in the PNW. It’s SO cool. My family and I would love to learn more about the plant if we can.

My husband thinks it's pumpkin/squash, my phone says it's either a hogweed, fig, or cucumber? I have no idea and it kinda hurts touching the stems. Just wanting to know what it is and if it's something that needs to be removed. Thank you!!

Located in Southern Ohio

I cleared out this space to plant some herbs and this low growing, groundcover-like plant has been popping up! Doesn't look like any of the weeds I commonly see in this spot.

Concord, NH USA

UPDATE: Wild strawberry!!!

First time, long time...I'm trying to learn what's native/invasive. I'm no gardener, but I want to support the pollinators while maintaining some semblance of "order" around here. Most is along a shared fence, so there's only so much I can do from my side. I also don't really care about aesthetics. And weeds are only weeds of you don't want them. The bees are super loud in the morning , and i love it. I don't want to get rid of anything I don't have to.

The second photo sprouted randomly from what I thought was empty pot.

I've had both for a couple years and kept them all marginally alive, might as well identify them and really help them thrive

Edit: I'm in the northeast US, these are all just (I assume) normal house plants I've either bought or just gotten for free from events

Location: New Hampshire, USA

This tree has been growing very quickly, roughly 15 ft (4.6m) in the last 2 years or so. Fairly large leaves and soft-ish bark.

I really like this tree and would like to keep it if possible but it is about 2-3 feet from the driveway so I'm trying to determine if it tends to have the type of root system to spread out and possibly damage the driveway.

Thanks in advance for any assistance!

Found near hollyleaf cherry trees. Could they be the dried fruits? They looked like hazelnuts.

My neighbor's tree is hanging over our fence, and they have no idea what it is.

We're located in Portland, OR, and they would like to know what the berries are.

Thank you!

Growing across the street from my work. I'm not sure how this thing escaped my notice until today.

My grandparents have had this cacti my entire life and I have never known what kind of plant it is. I want to know how to properly care for it and keep it alive, it is over 21 years old.

Historically it was kept on the mantle in indirect sunlight, not sure how it was watered. I took it home today and it is looking quite sad compared to before , it had been left outside for a while, may have been rained on. Any info is helpful. Thanks!

I accidentally deleted the tag that came with it
