You did say "germination" but for what it's worth, according to Arthur Kruckeberg in "Gardening with Native Plants of the Pacific Northwest;" "After flowering... young offset clumps will have already formed to replace the old. The offsets can be used for propagation; seeds are a much slower source of new plants."
hi KarinL i would be hard pressed to find any plants growing in scotland thats why im going to try from seed. i will be pleased even if only one germinates. thanks for the info.
Your best bet would be to sow them outdoors (winter sowing). They germinate sporadically. Seedlings seem to prefer the cool of outdoors. I lost a small batch growing under lights.
