Can someone identify this flowering vine for me?

It's very beautiful, and pictures don't do it any justice! I thought at first they might be Mexican sunflowers, but looking at some pictures has shown me they are not.

My mom has them growing along a fence in the back yard, and she doesn't know what they are. All I know is they are STRIKING!! I couldn't help but notice them earlier while they were bathing in noon-time sunlight.

Anyone know what they are?

That's lovely!

I wonder how invasive it might be....?

I've got a little fence in my yard I've been debating about trying to get something to grow on, and I KNOW I don't want Bouganvillea...

It's a very fast grower, and, due to its vine nature, hard to contain. Often grown on a trellis, or in a hanging basket. I'd give it a high grade in invasive-ness.

Hmm may not be a good choice for me, then.

I just googled it and learned it's related to Shrimp Plants! lol

I was actually trying to see if it's closely related to Kudzu, since that's what the leaves remind me of...
