I got the seeds at Southern Exposure, probably about 20 seeds in the pack. The variety is 'Thai Red'. They were started March 6, germinated in three days and nice 12" plants were set out May 11. As they need a long season of warm to hot weather for full calyx production they should do well here.
Here's a link that includes a good video on Roselle and the food uses for various parts of the plant:
