Mexicans Pings don't have a dry summer dormancy, keep them wet-damp all summer. It's winter when some go dormant and most others change their growth form from carnivorous to succulent, non-carnivorous growth. It's not really dormancy, just a change in growth strategy to enable the plants to survive the dry, cooler winter.
Yes, in the Winter, P. ehlersae likes it a bit drier than P. gigantea (this species does not form a succulent rosette).
Just because the plants are in a different growth form doesn't make them dormant though. There are numerous species of Mexican Pings that form succulent winter rosettes, yet they flower and set seed in this state, not what I call dormant (which is essentially asleep).
so could i just keep both pings in a terrarium there whole life? or could i put them out side in the winter. it gets about 20F the coldest in the winter?
thanks

I have heard it said that some of the Mexican Pinguicula have a drier, cooler winter in their natural habitat and that they have had success imitating such a variation in the environment they provide for their plants.
I am lazy and wanted to see if I could keep them successfully without all that trouble. I have had no problem, and no loss of plants, I keep all my Pinguicula in trays of water, with about 3/4 inch (2cm) of water in the tray, I let the water dry out and then I replenish it. The pots and plants never dry out, actually they are always wet. I am doing this even for plants such as Pinguicula gypsicola, P. moranensis, P. ehlersiae, P. esseriana, and many more. They receive a 16 hour photoperiod and they periodically change their growth form, but several can be in either phase at any particular time. I have, for instance P. potosiensis which is in the Winter leaf phase and is blooming including other images of plants growing in the same conditions. All of the following photographs were taken in the last few minutes.
That's fascinating Joseph, I grow all my Pings with natural light, so nature takes care of changing leaf form etc.
I have a small terrarium that I use to grow Byblis liniflora and a few tropical sundews, it might be a bit bright for Pings though. I think I'll pop a few spare, young plants into the corners and see how they get on.
Do you grow any of the SE USA Pings under similar conditions? I have a few tiny seedlings (1 week old) of P. pumila and P. ionantha which I suspect might fare better under terrarium conditions over the winter, than in my conservatory (min. temp 8C / 50F).
