    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.

    i stand corrected....let me rephrase: so the succulent/winter form is triggered by cool dry weather?

    Yes. Mostly triggered by those factors, but I've kept them wet, warm, and well-lit and still had some grow Winter leaves.

    However, I am open to discussion on the "dormancy" issue. Though I am mostly influenced by obvious hard evidence. In other words, show-me a "dormant" plant, and I will entertain the notion that these plants can be dormant.

    They do keep producing new leaves, just not the longer leaves, with the "grease". Same plants, earlier in the year:







    Late summer



    Spring

    Winter

    suite

    for the temperate there are a dormancy period .

    for the mexicaine it is a sort of dormancy , in reality a phase of reaction to hot periods.
    there is always a period to forming succulent or arachnoides leaves without mucilage but no possibility for them to catch prey and to digest
    The plant lives on its reserves (juice and water) .

    Sometimes they will make up "hibernaculum" or onions in these case it seems to me it is a real dormancy .

    here a P. heterophylla and P. macrophylla"hibernaculum"



    a P. medusina onion

    K Guys,
    I just received my first P. laueana in the mail today, and it is gorgeous!
    Now what? It looks to be in it's dormant stage and it has beautiful color so anybody have any tips I can at least start out with? Do I need to repot it now ( dumb question, I'll let it sit for a while).
    So again, any tips would be greatly appreciated!
    Thanks
    Marian (twotut)

    it is possible to repot , at this stade( succulent) you can make leaves cutting also

    for laueana a mineral alcalin substrate will be a good choice for the rest it depends to your culture conditions outdoor or indoor .

    my laueana pot



    succulent but also in flower
