Sedum seed is tiny and very hard to collect. I used (when my eyesight was a lot better) collect it for the Sedum Society and it was not easy to distinguish the seed from the chaff.
Sowing it, if you can get some seed, is fairly easy. Fill your pot with a good well draining compost, put a layer of tiny grit on the top, sow the seed on the gravel. Put the pot in water, leave until the water soaks in. No heat needed, just try to keep moss and liverwort at bay by watering with tap water.
As said easier to buy a few different plants and split them up. Go for Ss. acre, album, kamtshcaticum,spurium and other low growers. Also include some Rosularia, and of course a lot of Sempervivum and Jovibarba.
