It reminds me of jewelweed, Impatiens capensis, but I'm not confident. I don't know if they germinate year round down there?🤔

It appears to be woody, hirsute and it has opposite foliage, so not Impatiens. Can you show a close up of some of those buds? They look like flower buds.

Reminds me a bit of a wild ruellia...?

Sorta looks like a herb?

If you look closely there are little hairs on the plant

I mentioned it was hirsute above. I don’t know of any culinary herb which looks like this plant.

Here's pix of the top. As you can see there are no buds. And no hairs anywhere, the stems and leaves are smooth. floral_uk z.8/9 SW UK

No hairs?

This new picture looks nothing like the 1st one. Leaf morphology is entirely different. I might be hallucinating, but I don't think so?

You weren't showing, when I commented floral.

Jay 6a Chicago, floral_uk z.8/9 SW UK that pic does look entirely different.

It Looks like milkweed.

I didn’t suggest milkweed.

I meant with the whole picture not looking the same.

I will take that out if that causes confusion.

Leave it, don't worry about it

My apologies. I sent the wrong pix. Here's the one with the buds. The stems are rough but not hairy. The buds feel smooth in spite of the fuzzy look in the pix.

The wrong pix was for the Yellow Butterfly Vine (Mascagnia macroptera). One I've been wanting for a long time. It makes seed pods in butterfly shape!

Thanks for all your suggestions.

Thanks. Those are actually fruit rather than buds. And they look a lot like Ruellia pods as suggested by Carol above.

Perhaps Ruellia tuberosa?

Wow nice pic! :)

Carol, Floral, Jay

Your eyes are better than mine. It's the D#%! Ruellia , Mexican petunia. It's over running my gardens! I'm having some success removing it by stroking Roundup on the leaves. I put on a plastic glove and then an old sock I dip the sock in a small dish that I've poured some Roundup in. That way I don't have to worry about controlling the spray.

It's coming out of that pot and into the trash!

Mexican Petunia, R. simplex has longer narrower leaves than this plant. It still looks more like R. tuberosa imo.😬

It looks a lot like the wild ruellia I have in my yard. I believe it's a FL native. It seeds itself readily and has tough roots. The leaves on this one seem larger than the type I have, but that could be due to nutrition.

it does not look like Ruellia.

Maybe you are referring to the 2nd photo which isn't Ruellia, but the 1st and 3rd photos look like Ruellia imo.
