Mystery Plant

[MoldovaPro]

What is this plant? We found it growing in our watermelon pot on our patio in Maryland, near Washington DC. Any help is greatly appreciated!

That habit pic is fair. leaf detail, flowers, fruits and seed detail pics as well as stem structure and bark or xylem help even more.

It looks a lot like Mandevillea/Dipladenia except for the 1 tri-lobed leaf in the center.

When you say you "found it growing", does that mean the pot was there with no plant last year?

Google lens says Carolina Reaper on that last pic. Did you see fruits or flowers?

I think the stems too long for that idea.

The previous suggestion looks like this one.

What about passion fruit vine? Its a tropical. Has to have been helped to get up there.

This plant was not here last year and I have not seen any flowers or fruits yet.

I think its a Maypop or Passion flower or that family. Has the tendrils etc. I see a tri-lobed leaf but the boat shaped singles are not right classically.

Mandevilla plant is my guess

The leaves look like Mandevilla. I guess the scale makes the originals look very large to me for some reason.

I think different varieties have slightly different sized leaves.
