Mystery Central American plant...must I.D. soon!!

vtjaneMay 3, 2014

In a recent trip to Central America, I came home with a few hibiscus seeds, a couple "nance" fruit seeds, a bunch of celosia seeds, and one mystery seed which I cannot recall!! I remember being given each of the other seeds by friends I was with, but this one I can't remember at all. I put it in some potting soil, and it germinated and grew quickly. I want to make sure I can ID it before I even think about putting it outside though--last thing I want to do is accidentally spread something that could be invasive.
I have a picture with the seed (along with nance and jamaica hibiscus). The mystery seed is black or very dark brown, and sort of oval or vase shaped and pitted. About half an inch long.
I tried emailing somebody in Honduras who might know, he or his family probably gave me the seed, but I haven't heard anything back.

Can you post a pic of the seed as well?

That sure reminds me of Four O'clocks (mirabilis)

Yes, it looks like that! :) The seed is the dark one bottom left of the attached picture (I tried uploading multiple pics on my first post but didn't succeed).

I live in Vermont. I don't to plant something outside in my garden that will take over--sounds like 4 O'Clocks are common enough for gardens though? Any tips appreciated!

I was worried it might be a fallopia, related to Japanese Knotweed, but then it (in the Polygonaceae family) would have alternate rather than opposite leaves.

I think the seed on the left is a 4 o'clock.
