Very nice clumps, Claire! I have only one small Trillium in bud - but it is in my greenhouse! (So even in the greenhouse it is a late spring :-\ ) Outside I can barely see just a little sign of life in my small clumps. I also have some nice pots of different seedlings sown the last couple of years. They all germinated at the same time last winter (Dec-Jan).

Claire, did you separate the seedlings or plant it in one clump?

I confess -- I plopped the whole pot of seedlings in the garden one day when I needed more room for other seed pots.  I haven't had to divide or move any of them, thank goodness.  Laziness (or desperation, in this case) luckily paid off.  :)

Lovely bold clumps Claire.

Nothing like that here ----I think i may have to stop dividing /collecting seed each year .........

Cheers Dave.

Those clumps are phenomenal, Claire! I am waiting to see if the T. albidum and chloropetalum seed from the seed exchange germinates. In the meantime there's a raft of Trillium luteum  and T. grandiflorum, getting established in the greenhouse. Once the temperature warms up enough, some will head out into the woodland garden, to join T. kurabayashii and T. erectum. Maybe this will be the year I can find T. undulatum in our woodlot?!

Good luck finding T. undulatum -- post pictures!  That's one trillium I killed the first year I had it.  :(

Maybe they like to be crowded?

Too much crowding is not a good thing.  Right now, along my front walk, I have large clumps of Trillium kurabayashii that are crowding out each other and everything else in the bed.  Does anyone have a recommendation on when is the best time to move most of the trilliums out?  I have a conglomeration of seeds, first-, second-, and third-year seedlings, and mature clumps.  I know, lots of people would love to have my problem.  But it can turn into a problem of virus, fungus, and who knows what else, if I don't get better air circulation around the trilliums.

So, when is the best time to move trilliums out of a planting bed?

Having had experience with the sessile group of Trillium for over a decade with all the species native from Kansas south and eastward I would say while the mature plants are in flower is best. This is when the new part of the rhizome begins to extend and thus the new roots are just coming out then. Then you have the option of the fall when these new roots are putting out their branches for the next seasons new growth. Trillium seem forgiving in this regard, but they can be set back for several years if they are mis-treated.

Thank you for the advice.  I tend to move trilliums when they are in flower (right about now) -- it's good to hear from another about their experience.

T. sulcatum crossed with T. flexipes and the resulting seedlings are pretty nice, with some picotees and others more pink than maroon.  Here is one example:
