Hi. I would not describe that as a typical low-growing (creeping) sedum. I think the reason it looks somewhat vine-like is because it is “leggy”, a term that describes plants grown under light conditions that are lower than they prefer; this results in distances between leaves (internodes) that are much longer than they would be naturally. Low light levels are a common problem with succulents grown indoors, as noted on this page from Iowa State University. Sedums prefer full sun and are adapted to hot, dry conditions; if grown indoors, they should have 6-8 hours of bright light. Here is a good page on sedums from the U. of Missouri that you might find useful. Your plant looks similar to something like ‘Autumn Joy’, a very popular upright cultivar that is now technically placed in the genus Hylotelephium. However, the leaves seem more rounded, so it could easily be something else, especially since many new cultivars have been developed since 'Autumn Joy' was introduced more than half a century ago (1955). Confidently determining the specific cultivar of a plant like sedum can be challenging (if not impossible) without genetic information, but when it flowers, that may provide some additional clues about its identity.

Thank you very much. Your response is extremely helpful.
