One picture: epicotyl dormancy
Sanguinaria canadensis: seedlings of last and this year in the same pot = keep your pots for at least 2 years.
Cycles require for germination (moist at all times): W + C with about 50% of seeds with W + C + W (W- warm, C- cold). From a small sample of seeds you may never know, they can germinate all at once or in stages.
The epicotyl dormancy can be simple or double simple.
Sanguinaria canadensis 2 generations seedlings
Simple epicotyl dormancy = emergence of the roots in autumn and emergence of the shoots following spring; a germination pattern common for many species.
