Trilliums from seed

[GordonT]

Veronique, Any pots of seed without any seedlings showing, may still germinate. I would advise sowing seeds in pots that then get sunk in your garden (without any special protection) for the winter. I did this with extra seed I had of Trillium undulatum, and now I have a new challenge on my hands, how to separate a "Lawn" of Trillium seedlings (photo was from last year).


It is even more crowded this year, so I will have to try and give the plants some space.

Oh ! amazing Gordon!    it's all a small lawn ...

Yann, do you manage to germinate and cultivate Trilliums at home?

Yes i've few ones in the garden for many years, i mostly sown for friends or swap but i don't keep seedlings. Sadely the garden can't extend itself. I let the pots outside, north facing without any protection and germination occurs in 2 seasons. T. rivale is usually the first one in less than 14-15 motnhs. Fresh seeds i was given were put in frigo in plastics bags+vermiculite for 2 months and then sown in october while it's still warm. They need 2 cycles cold/warm. Slugs can kill full pot in one night, that's my main problem otherwise like paeonies it's just a question of time but it's not complicated.
