How to germinate Trillium flexipes seeds:
Dry seed. Soak 12-24 hours. You might want to remove the elaiosome by gently rubbing in a cloth. I’ve had very good germination when this wasn’t removed. Our spring sown Trillium seed typically germinates by late September. Sow 5mm deep with a thin layer of mulch. Sowing medium should be humus rich well draining and slightly acidic. Never let fall sprouting seedlings freeze. We keep our trillium pots in an unheated greenhouse over winter. This reduces bloom by a year or two. Never give the kids strong hot sun and poor dry soils
