Marc, I have been on Holiday in Italy, so I have been less on the forum. You have an interesting method. How long are your cycles?....quote]Herman,I use 12 week cycles. I place 4 or 5 tbsp of seed starter in a ziplock bag, add the seeds shake, add water to dampen [not wet] the soil. First I hang the bag on a grow light with a clothespin, then I refrigerate it. Germination usually occurs on the second light cycle; but, sometimes on the second cold cycle. Starting in the second light cycle, I check twice a week for sprouts.I drill holes in a dishpan for drainage and fill it with equal parts of sand, gravel, leafmold, and potting soil; and place 2 pans under a grow-light. Under the pans are planter boxes with gravel. I sprouts into the dishpans as soon as they are detected. I use the same method .The water evaporation from the planter boxes under the pans protects the seedlings from the dry air indoors.

I don't know how it happened!

It is intensive work, but with perhaps a better germination result. For me, the germination is irregular, but in the end, depending on the amount of seed in the pot, there are usually enough plants left for the garden. Germination is easiest when the seed is very fresh.
Very impressing, how do you prevent hybrids? Do you?
Axel, planting in groups, some distance between the groups (shrubs and other plants between them), I alternate between pedicellate trilliums and sessile trilliums. Keep in mind the flowering period, there can be a month difference. If a hybrid appears in the same place, I will transplant it, if it's a nice one.
Herman - your Trillium clumps are fantastic!I sowed the seeds of T. sessile I got from you directly in the ground and they all germinated. I intend to leave them like that, maybe one day they transform in a large clump (Attachment Link)
