Here they go!

Trillium grandiflorum seeds are just beginning to germinate! As well is Paris quadrifolia; I noticed the first signs last Saturday (with my x40 lens).

I snapped a few pictures when I was packing some today; they are advanced enough to be noticeable even if the pictures are not great.

Trillium grandiflorum seeds starting to germinate

No matter what someone else says or writes, this is happening every year.

For these species, moist stored seeds kept at warm (room temperature) will always start to germinate around this time (roots only).
From all T. grandiflorum seeds, 70-80% will germinate now (roots) and then show the first leaves in the spring after a period of cold stratification. The rest will need one more warm/cold cycle to go through the same cycle.

Paris quadrifolia seeds were also tested two years ago and at that time they all germinated by November (this year I only got few and were promised to someone).

On short, hurry up if you think about Trillium grandiflorum; right now I can select and send seeds that are just about to germinate (they are enlarged and lighter in colour – see the feature image).
