How does asian jasmine propagate?

Question:I planted asian jasmine a couple months ago as a groundcover. I am now wondering how it spreads. I know that cuttings can be used to generate new plants, but does this plant species also spread by another method (i.e. seeds or something else)?
The reason I am asking is because I now have lots of little weed-like plants growing in the same area as I planted the jasmine. Normally, I would just assume they were weeds and pull them out. However, I have never seen weeds that look like these and they are not present anywhere else around my property. Also, I never saw these prior to planting the jasmine. Can these be seedlings? If they looked exactly the same as the jasmine, I would obviously think the answer was yes. However, the leaves look slightly different- these small plants have leaves with slightly rough edges, whereas the larger plants do not. Any ideas?

Answers:
Wherever the vine touches the ground, it can set roots. I'm not sure about Asian jasmine but, on some of my younger star jasmine some of the leaves have a different shape. Not that this has anything to do with jasmine, but, I notice on different trees, like some of my scrub oaks, first year growth is serrated, not smooth. So maybe your jasmine is the same. I would wait a few months to see what it is before you pull it.
