Yes. It seems to be the straggly cultivar of sedum rupestre. They are new, so i cannot provide a lot of info...

Likely to be straggly due to inadequate light levels - a problem all succulents being kept indoors often have

Not really. Ive seen these circulated arround. Grown in full sun, yet they look look as if theyve been kept in a basement. It is possible that it may be something else too...

While some could look quite 'untidy' - I believe yours is really etiolated. Hardy succulents should be grown outdoors year-round, receiving proper amounts of sunlight, that is when they will look their best. Even the scraggly ones :)

This one is kept outside. It’s very cold hardy.
