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.

Please excuse the duplicate post. I don't know how it happened!

Wow Marc, your method is impressive. 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.

Herman,

By holding the seedlings indoors until they gain some growth, I protect young seedlings from: turkeys, moles,voles, gophers, slugs, and insects. Protected from predation they get a good headstart before they have to face the real world.

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.
If you want to be very sure it is hand pollination. If I don't need the seeds I remove the berries. When the group is large enough, I remove any emerging seedlings.

Herman, You´re lucky to own a garden large enough to grow such an impressive collection and manage it in such a deliberate way! Also,  obviously all species do well in Your garden. On my heavy clay, I have far more success with the sessile ones than the pedicelate species.
The variations in Trillium luteum You show is fascinating! Owing only a smaller garden, I prefer the more showy ones, as the deeper yellow one of Your last picture.

Though I grow trilliums since about 25 years, I never noticed any self-sown seedlings. I think there are some hybrids among the plants I grew from seed, but as long as they are nice I´m quite happy to keep them.

Trillium mixed seedlings from a kind forumist in NZ. Unflowered to date so identification is beyond me.   Anyone have a guess which species they might be or are they indeed a mix? The second shot shows a strongly marked one.

Can't get larger pix to upload though some folks can have them enlarge in a different window but I've never been able to.

Herman, your Trilliums are growing so well!
Thanks for giving the idea how to keep species separate, though I don't have that problem (yet at least), but it would be nice to have as good groups as you have.
Mine are mostly T.chloropetalum or its hybrids, but as long as they are growing well I love them and they are showier than T.erectum which also grows well here. Still, all plants are nice. :)
Trillium luteum is also very nice, and I like how it flowers later than others. It's yellow is so lovely. I have couple of seedlings from your seeds, Herman. :)

John, really nice foliage. I have also some plants from Dave's seeds, and they have nice foliage indeed, and pretty flowers as well (the ones which have flowered so far).

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 :)
