Identification Needed: Vine-type plant, 5-lobed leaves

Hi guys,

This plant is growing in a pot in my boyfriend's family's backyard. It was given to his mother as a cutting, so we have no clues as to its identity.

We live in Southern California.

It's a vine plant; it has no flowers or fruits so far.

Does anyone know what it might be?

Thank you!

 

Might be Echinocystis lobata.

 

It looks like Ipomoea batatas to me - sweet potato vine.

 

It does look more like sweet potato.

 

Ah, thank you guys so much! I think it is sweet potato - it looks like a good match and that would make sense if it is.

Here's to hoping it blooms someday - the flowers look like they'll be lovely!

Thanks again! :}
