so just to clarify---for myself that is, mexicans need cool dry dormancies like petiolaris dews?
Contrary to popular opinion (and the authors of several books), Mexican
Pinguicula do not go dormant. Dormancy is when a plant ceases growth - like deciduous trees in Winter. Mexican
Pinguicula change leaf forms, it's why they're called heterophyllous, but they do not cease growing new leaves. Many species even bloom in their Winter leaf form. Blooming is not an indicator of dormancy.
I grew all of my Mexican
Pinguicula species and hybrids in wet conditions, year-'round, for more than five consecutive years, without any adverse consequences. Rather several positive consequences. I still recommend my favorite growing method -->
Growing Mexican Pinguicula.
****************************
For most species and hybrids, the most important environmental factor that stimulates blooming, is a wintertime drop in nighttime temperatures, into the 60's, 50's, or 40's Fahrenheit.

Pinguicula laueana is a very attractive plant even when it isn't in bloom. Here's one in Winter leaf form (not dormant). In the top center of the photo, an aerial root is visible poking out from between Winter leaves.
