A small woodland gem from our west coast. Pink to white flowers are randomly dotted with the darkest pink. Mid green mat leaves have white veining unique to this species. Like Paris, its not considered a true Trillium but an ally. I find it easy to grow and it loves growing in clumps in the rock garden or in pots.

How to germinate Trillium rivale seeds:
Fresh seed. Our spring sown Trillium seed typically germinates by late September. Stored in moist medium, its best to add a little more moist medium and keep in the side compartment of your fridge at 2-4C until you are ready to sow. When you are, sow seed 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 the winters and bloom time can be reduced by a year or two. Never give the kids strong hot sun and poor dry soils. Prefers dappled shade and cool locations.
