Tamlin, Your amazing!
I'm stratifying the follwing:
D. intermedia "Rhode Island"
D. intermedia "Giant"
S. purpurea spp. purpurea
S. purpurea spp. purpurea f. heterophylla
When it warms up a bit I will starting more plants
D. spatulata "tamlinosa"
Just noticed today - P. ionantha and S. flava have germinated! (1st success I've had with either Pinguicula or Sarracenia seeds![img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img]
Seeds of P.caerulea do not need stratification. Just sow them in a warm location. If they are fresh germination should be fast, otherwise it could take some time...
