Like Phil, I also just cover my Sarracenia seed, but with chopped
spaghnum as Slack recommends. Before sowing though, the seed
is thoroughly mixed (and stratified) with the chopped moss, and is
then spread over the surface of the growing container filled with
spaghnum moss.
Even though the seed is covered, I suspect enough light infiltrates
the gaps in the spaghnum to assist germination. I usually get
better than 90% germination using this technique.
As Phil also mentioned, Sarracenia seedlings are susceptible to a
hot, dry environment, and will quickly die if exposed to these
conditions (as I have often found!!!!!)
