Hi Jeff, I've kept the same plants thriving in cultivation for as long as three years, except for P. pumila which is a strict annual and usually "flowers itself to death" after one year...  Happy Growing, Brian. |

I knew for pumila ( it is necessary to fertilize the flower to have others plants by seeds )but for the others you say just 3 years  |

Hi Jeff, Yes, that is true! ;D Unfortunately I experiment too much sometimes... Although at times, I do believe the plants actually "flowered themselves to death" I usually keep seedlings going of species year-round just in case. Brian. |

Hi Jeff and Brian, I am growing the same Pinguicula caerulea plants for already 8 years now. I was told in the wild these plants never become that old. I have to admit these old plants have shrinked in size muchly after their fifth year of life. And this spring was the first time the plants also didn´t flower. I guess the plants won´t stay alive for much longer. Maybe another season but then....? Flowering itself to death is a phenomenon also reported about P. lutea in cultivation. I think it was even Andreas Wistuba who told me about it. I never grew this species so far. Daniel O. has some more experience with Lutea I think. Regards, Andreas |

Hi my friends  , my P. primuliflora i´m growing now for almost 11 years or longer, the mother plant itself never died and it´s flowering every year at almost the same time (the first flower has opened these days) . My P. ionantha seems also not to make any problems after some years. They are pushing a lot of flowers every winter (up to 8 or more), but after some time they are stopping to flower. Some of my other older clones of P. lutea have never flowered to death, under my conditions they are producing about 2 flowers every season. About P. planifolia i cannot say a lot, my first flower will open these days.  Only P. pumila is flowering to death, but it´s annual, so it´s no wonder. 3 years ago i received 3 plants which have been in full flower, but i did not managed to pollinate them and after 2 months i lost them (i have not known that they are annual).  I think that the only problem can be that after several years the substrate is too exhausted (no minerals at all) and than the plants are starting to produce shorter leafes and perhaps they don´t have the "power" to flower and than they are dying. Two of my older P. lutea were going to die a few months ago (they have been growing in the same substrate for about 2 years, perhaps even longer, because i received them potted), after i gave them 1 coin of osmocote they have started to produce longer leafes and they are looking much more healthy. Best regards and a happy new year, Dani |

many thanks for these infos.
perhaps an other on the seeds viability ? have you some experience on old seeds ?
is it necessary for a good seedling to have fresh seeds?
happy new year at all ;D
