Hi All
Last winter I had some problems with hibernicula of artic P. vulgaris. The winters are not long enough here in Belgium, compared with the winter in their habitat. So they grew too early in the season and went too early in dormancy ( mid summer) so I finnaly lost them. So I sow some new once this summer and need to hibernate them now.
I wonder if I can put those hibernicula in the refrigator too prolong their domancy.
I tought to store them in moist Sphagnum moss in small plastic zip bag untill may.
Does anyone has expierence in hibernation of hibernicula using this method. What could be an other option to hibernate them.
Best regards

I am wondering if your problem wasn't the short winter but the summer temperatures were too warm. Temperate Pinguicula hate hot weather. The low winter temperatures here in the UK lasted well into a very late spring, you're not that far from us.
As for storage, P. vulgaris hibernacula usually pull themselves well into the medium to overwinter so I see no problem bagging and fridging.

The weather of the UK is altered by water currents and is not representative of European weather

How much longer does dormancy need to be? And fredg may be correct in that it is the summer heat that is too much.

Well we didn't had aWell the plant if from near Alta, Norway, quiet up north. This one started to grow very early, bloomed very fast, produced seeds and straigt away an hibernicula. On the other site P vulgaris from 2000kms down and P grandiflorum grew normal and went only dormant about a month ago.
So I wonder

On the other site P vulgaris from 2000kms down and P grandiflorum grew normal and went only dormant about a month ago.
Is it possible to pack it in the way I think?

Hello Teinkes - It's an interesting question you pose. Many wide ranging species have ecotypes that are adapted to local conditions. It's not uncommon for the phenology of populations of a species to differ from different latitudes. I am not aware of any studies that specifically look at this issue in carnivorous plants (though I must admit I didn't look before typing that last sentence). Still, we do know about local adaptation in several CP species in regards to populations that vary in their capacity to form dormant buds. I don't think it would be a stretch to find that some species have different phenologies also. In some ways it's less of a difference. So you may well have identified that P. vulgaris has locally adapted to the season length in your own little common garden experiment. As far as what to do about the northern population's maladaptation to your climate - I'm afraid your guess is as good as mine. I've not had to deal with this. In my climate I mostly worry about extending the season for species. Good luck and keep us posted on what you figure out.

If you use a ziplock bag, be sure it is open a little so it doesn't suffocate

Ok i'll put it in refrigator for the whole winter. some moss around the hibernicula and in a open ziplock bag.
OR I just tough wrapping in toiletpapet / tissue so it can breath or even just put the complete pot in the refrigator. I am worried for fungi, so i' will treat it before, then in te refrigerator.
We'll it could be nice if people allready did some expierence with this. Some more tip how to store hibernicula would be good to learn from.

Bob - Do you look these things up or do you simply have an encyclopedic knowledge of the entire CPN library?  |

When you are the editor of the thing, one tends to remember stuff.

Hi Bob - Somehow that the answer effectively was encyclopedic memory doesn't surprise me.  |
