Help Identifying this plant??

These plants are from seeds that I found and planted. I thought they were some sort of citrus, but now I am not sure. The are not doing that well, so any advice would be greatly appreciated!
Thanks~!

They remind me of Passiflora edulis

 

Thanks for any help. The leaves edges are smooth. I also took a pic of the seeds before planting.....maybe that would be helpful?

thanks again,

Artie

Plants do look like passion vines.
