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.

I don’t really know why but I got really excited when stumbling for the first time upon Medeola virginiana. As a result, the pictures don’t show its whole splendour revealed under the dappled shade in a moist woodsy area. Named after the sorceress Medea, there are few theories as to why Linnaeus kept this name (given to it by Gronovius) but there is no doubt that there must be sorcery involved in the way a fruiting Medeola looks.

The contrast made by the dark purple fruits with the red petioles and red tinged leaves (at the base) is striking and considered its most ornamental feature. Young plants resemble a bit with a Trientalis for me, or a Large leaved pogonia (Isotria verticillata) to others (I have never seen this one). Mature flowering individuals are very particular though, showing the two-tiered whorls of leaves. I think the flowers are pretty cool too, as seen in the featured image (not my picture in fact, but coming spring I know where to go now).

And the trivial: the common name, Indian cucumber-root, alludes to the fact that rhizomes have a cucumber taste/odor and were used by the Natives Americans; the plant was also supposedly used medicinally. In Canada apparently we don’t have problems with it but in the U.S.A., according to NatureServe, Medeola is listed as critically imperilled in Florida, Louisiana, and Illinois.

Either way, I think there are enough cucumbers on the market today, there is no need to dig up Medeola, which is vulnerable to harvesting and slow to propagate.
