Back in May my P.grandiflora flowered and for the heck of it I pollinated them with a small toothpick.Well, out of the 4 flowers 2 took and I have been watching them everyday until they were dry enough and I knew for sure the pods had ripened.
After a storm lastnight I went out about an hours ago and one had split and must have been knocked around in the storm and it didn't have any seeds in the pod but the other one has a bunch !!!
Whoo hoo !! Anyway, do they need a cold stratification period or should I plant them right away?

Right away,
I am not aware of any Pinguicula which have a stratification requirement.

Right away, I am not aware of any Pinguicula which have a stratification requirement. I am. P. vulgaris for instance won't germinate without a cool period and for really good germination needs even frost. Grandiflora is easy and will probably germinate but sort of a winter period should really increase germination. |

Hey Marcel,
Thanks, do you have any other species which need a stratification period?

Basically all European species will benefit from a colder period.
Think about species like the longifolia's, leptoceras, balcanica, etc. Even "warm" Europeans like vallisnerifolia have a cold period in their native habitat.
Only exception that I know of is lusitanica, but that acts most of the time like an annual.

I believe P. macroceras and P. villosa also require stratification.

Have these species actually been tested? All the species I'm familiar with drop their seed before summer even starts and the seed start growing; and they are all temperate. P. macroceras finishes flowering by now and are dropping the last of their seed. But the seed is going to stay dormant until the end of next winter?

With the exception of alpina and vallis-regia I grow all temperate species. All (with the stated exception of lusitanica) will have bad or no germination if they don't get a period of cold. Macroceras and villosa are borderline cases to be called temperate. For my self, I have macroceras only for a short period and can't therefore say much about it's behavior. I don't consider villosa temperate (but that is my opinion)  |

I had one of my macroceras plants produce seeds last year and the seeds I tested to see if the actually would grow germinated without stratification grew very quickly(within 2 weeks).
I think I'll plant a few of the grandiflora seeds and see how they do.
