    beautiful plants, they are hard to come by here in AU, same with N.Tenax and Rowanae, they are native yet are almost impossible to get in AU, also although most petiolaris die down in the dry season I have seen wild Lanata growing in the heart of the dry because they found permanent wet seeps.

    Excellent growing! That D. linata is a beauty. Thanks for sharing your setup, its always nice to see how others grow their CPs.

    Happy growing;

    They are slowly and painfully killing you.....did you know that?

    How brainwashed are you?

    That is news to me and I've never heard of low light levels causing dormancy in other Drosera. Petiolaris 'dews are different in many ways, it seems.

    I'm surprised that they are hard to come by in Australia. I believe there is a vigorous CP community there. 'Cool that the D. lanata plants can grow through the hottest of the summer given water. That would explain their love of heat.

    Yep, that is from the growing experiences of the growers here. We all thought it was temperature at first but we are hot year round...hardly even warm by temperate standards. The plants go dormant at about the same time as the Vfts and Sarracenia and after checking with each other, we do think light plays the biggest part. During the year end, we have reduced light levels because of the rains. And also since most of us are apartment growers, a change in season sometimes mean light no longer shines directly into the growing area for a few months. We haven't been able to validate the "theory" as there aren't that many garden growers who have their petiolaris complex plants growing in the open to compare with. These plants are hard to come by so most of the growers keep them indoors and protected from the torrential rain. LOL

    Cindy - It would be interesting to try out lowered light levels under artificial lighting and see if one gets the same results. On the other hand I avoid dormancy like the plague. As you mentioned you never know if the plants will wake up at all. I have heard that there are growers who induce/allow dormancy year after year. Do they just deal with the losses or have they figured out how to minimize them? I wonder.

    D. paradoxa temperature question

    Drosera paradoxa is the most tolerant, or at least one of the most tolerant, petiolaris sundews when it comes to cool temperatures. They will continue to grow in temperatures that have other species completely shut down and dormant. Has anyone watched D. paradoxa become dormant due to low temperatures? If so, at what temperature did the plant(s) become dormant?

    Hi mark, there is lot of literature pertaining to the plants going dormant in summer in the wild. But I haven't read anywhere that they go dormant with low temperatures or low light levels...These are experienced by temperate and tropical growers as well. Have you come across any literature about cold dormancy?

    Hi, Cindy. I haven't, and I'm just assuming that dormancy could be induced this way. I make such an effort to ward off dormancy that I have only seen two species go dormant and never D. paradoxa. Having done some quick reviewing I've found one source, the AIPC publication The Petiolaris Complex by Maurizio Saroldi, states that D. paradoxa remains growing in a diminished form during the dry season in its natural habitat. This makes me wonder if this species has the capacity to go dormant. Have you seen it do so?
