Breaking the tradition – Medeola virginiana germination
More updates on germination requirements
It seems that Medeola virginiana seeds don’t follow the traditional double morphophysiological dormancy (MPD). Unlike most species with this type of dormancy, which require a cold-warm-cold cycle to germinate and produce roots in the warm period (2 years seeds), M. virginiana seeds do not form a root during this time; instead, root and cotyledon emerge at the same time in the second spring after sowing.

Speculations are that this sort of germination pattern may represent a transition towards a type of more complex MPD.
Or is it sorcery involved ? ;-)
OK, the practical meaning of all this: be patient and don’t scratch the pots looking for tiny roots in the first year.
For me: I could keep the seeds in moist storage until the second spring, if I would have that many…
Note: again, we are talking here about sown fresh/moist kept seeds.
