Oh good! I thought you meant you were just now planting the pardalinum seed. Since you have already planted them 7 weeks ago, leave the outside. They will sprout in their own time under normal conditions that they would get in the wild. This is far better than trying to coax them with artificial methods.
The martagon and bulbiferum seeds don't need any cold to germinate the seed. But the cold can't hurt them, and may help them germinate more uniformly when the time is right. They will germinate when it is warm, 60-70F, and produce their tiny seed bulb underground. They won't grow any leaves until the following growing season, after they have experienced their cold treatment through the winter. So this year, you will have pots of live martagon seedlings, but nothing that shows above ground (no leaves). Occasionally, one might send up a leaf prematurely this year, but 95% of them won't.
