Hello! Here's some info on forcing Sedum to bloom from my botany textbook, in case you want to do this someday in the future for a bouquet of flowers etc. (This is not a direct entry from the book)
Sedum (and relatives) are long-day plants and will bloom if the photoperiod (how much time it gets good light) exceeds 13 hours.
Hope this helps,
Sedumzz
