Has anybody got a clue?

Heart-shaped leaves remind me of morning glory, but I'm thinking mg has a smoother surface; maybe a relative?
vey lush & pretty anyway!

Perhaps a menispermum (moonseed)?

Sylvia, thank you for being willing to make a suggestion, but Molly, I think you nailed it. Much appreciation! Images of Menispermum moonseed in Texas

gorgeous!

It is gorgeous!

Awesome

Well, I'm not sure yet if it's the same vine, but one with very similar leaves is growing rampantly at my sister's house and has almost smothered her roses. What a mess pulling it off and I'm only half done. It has very small yellow flowers. It's been coming up at my house too and is quickly pulled. It is not one you want seeding itself around. Will try to get pictures.

First of all, I told G that I was going to ask you if you still had a pic of Georgianne's greenhouse and then I see this, lol

Anyway, try googling creeping cucumber and see if it the flower. the leaves sometimes look different. They are very invasive

Yes, those are the little yellow flowers of the vine trying to take over the world at my sister's house. And you're right -- the leaves of the Creeping cucumber don't look like the leaves on Georgianne's vine.

Funny about the greenhouse showing up in the picture above. Whenever you come down we can take a tour of Georgianne's yard.

Thanks Jolana!

Found the post I did about her greenhouse:
