Is it even possible that this is a fuchsia that came up by itself at an abandoned house in Pittsburgh??
The flowers are closed but they are obviously tubular and believe me they are a deep hot pink when in the sun!

Looks like Four o'Clocks (Mirabilis jalapa) to my eyes.

Wow, you were RIGHT there when I posted!!!
I'll look that up -

You may be right.
I think the seeds from mine are larger than the seeds in the post by @flaflwrgrl
But @zencat has that shot of the hummingbird that looks REALLY right.

And Marvel of Peru (Mirabilis jalapa) says zone 7!!!!
This plant came up on a northeast facing wall of a house on a north facing hill!!

I'll leave the question open to others until I'm sure.

Critter, Four O'clocks are considered an annual in far northern zones; but the plants readily set seeds; so, save those seeds for next season.

And, I've seen seeds of all sizes on M. jalapa

I say that's Four O'clock. No doubt about it. Lucky you finding fuchsia ones! My seed photo was of the seeds from a package I had bought @ Dollar Store & no doubt were not "the pick of the litter" so I'm not surprised your seeds are larger but the seeds are very distinctive in shape.

I also recognized those seeds as M. jalapa. Pretty plant; good find!

No doubt about it, that IS Mirabilis jalapa. Good find!

On that note and slightly off topic, I always have spare seeds from my fuchsia 4 O'clocks. If anyone wants seeds, Tree Mail me.

Yes, that looks EXACTLY like the one (!) Four O'Clock that I was able to germinate out of 12 seeds... and which actually opens its flowers at more like 10:00 (a.m.), not 4:00 !!

Funny, Sandy. Mine open up around 6 pm. I wonder what time zone they are on?? The flowers smell divine! The plant forms huuuuuge bulbs, some larger than a cantaloupe! My seeds self-germinate and I am constantly pulling up volunteers.

"The plant forms huuuuuge bulbs"

Yes, I've read that they make big tubers -- I wonder if I could over-winter them like dahlias? (Mine is in a pot this year, so I'm not at all sure that it has much in the way of tubers, but for future reference...)

Yep, it Four O'Clocks for sure.
I collect seeds from several places in and around Savannah, that pink color is popular here; offer them for trade during the Piggy Seed Swap on Cubits.

Mine overwintered just fine in the ground. We get frozen ground in winter and these came back. I never saved any seeds tho.

Well OK then!
Mirabilis it is!
I'm still astonished to have found it on that seriously exposed North wall!!
It survived, either as seed or bulb the polar vortex winter that killed all my buddleia (lower zone tolerance in more protected area)!

And you betcha I'm saving seeds!

I only have 5 seeds!!!
But after I grow it here next year, I'll have more!

Four O'clocks became very invasive at our old house. Some of the tubers do get really huge and very heavy. We dug out many of them a few years ago that spread about 8 feet from our fence out to the street and through the side and back yard along the entire length of the backyard. They sure were pretty but began to take over and cover other shorter plants killing them out. We had lots of the dark pink variety but there were hundreds and hundreds of the white flowering ones which seemed to get a lot taller and the tubers were a lot larger also. These are some of the smaller tubers that we dug up and a photo of the pink variety:

Lin, it wouldn't take Mother Nature long to completely take over Florida if the residents didn't keep fighting her back! (ditto for the other southern states as well...)

I've lived in Florida for 47 years and it's a never ending battle ... and don't even get me started on the subject of weeds!

True, true.
