I have a couple P.macroceras plants that have or are starting to flower.I was wondering if others have had success pollinating them.
Thanks in advance,
Mark W.

Yes, a few years ago I had seed develop from self-pollinated plants. The seed were viable and germinated quickly, even without stratification.

Joseph,
Thanks a bunch for the info.I wasn't sure if it could be self-pollinated or not.So, they will germinate this year without going thru a winter stratification? Will the grow enough to develop a good enough hibernacula to sustain an cold Iowa winter?

I ended up trying to pollinate one of the plants and one of the numerous heavy rainfalls we have been experiancing here in the Midwest ended up knocking off the flower.The other two plants ended up being pollinated by an insect so the seedpods matured and I ended up with quite a few seeds.
I dried most of them on a petri dish with a small piece of paper towel and put them in the fridge for later use. A few of the remaining seed I put on top of the pure peat media and put them under lights.
Like Joseph said they germinated after only 10 days under light amongst my Mexican pings.
Thanks for the tips Joseph !!

Hey Mark,
Do you know the location of origin for these plants? State, province, country?

Pinguicula seed does not stratify, it starts growing immediately. I'm not sure if some seed do stay dormant and then start growing the next spring, but this seems a rather unlikely Stanard Operating Procedure to me.

Dave,
I haven't got the experimental evidence to back me up, but surely temperate species would have seeds that require a winter stratification to germinate? These plants produce seed in the fall, shortly before winter snowfall. I would think that evolving a winter dormancy would be an advantage for them?

Dear Barry,
Well, I'm not familar with P. villosa, but P. macroceras flowers in the erly spring and the seed is ripe and falling to the soil/wet slopes by the end of spring. I haven't found or heard of any Pinguicula species that do not follow this pattern.
Some species from near the equator can flower several times a year, but then these seeds would not go through stratification regardless season since the climate doesn't actually have a freezing season.

Hmm. On reflection I think you might be right. But still, I've grown P. vulgaris from near the Arctic circle. I wouldn't be surprised if they required a stratification period. Unfortunately, I never obtained seed from them.

Barry,
I bought the plants from Sarracenia Northwest.I'll have to ask them if they have any of that info.

Barry,
I just got off the phone with Jacob from Sarracenia Northwest and he said they were actually macroceras subsp nortensis.

It's a pretty plant. I hope you have good luck with it.
