    I keep hearing/reading all the time on many CP forums that "seedlings of VFTs or Sarracenia dont need a winter dormancy for the first year or two"..

    im not saying that is wrong, because I dont know..
    but I do have to question it..because it defies logic.
    where did this idea come from?
    did someone just make it up and now its believed as fact?
    or is there is there good solid evidence and experience to back this up? if so, where?

    in the wild, all sarracenia and VFT seedlings get a dormancy their first winter, without fail..if the adult plants require a dormancy (which they obviously do) why wouldnt seedlings also require a dormancy? why would seedlings be different from adult plants as to dormancy requirements?
    I would like to know where this idea came from..
    it worrys me that it might be an "internet rumour"
    this concept only seemed to appear in the last year or so, I dont recall ever hearing about it before, and I dont think it is in any books or the ICPS journal (although ti could be, I havent personally read every issue of the journal! [img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img]
    anyone ever seen it there?

    thoughts? personal experience?

    thanks,
    Scot

    In the same way that tissue cultured plants, you can give them dormancy if you want and that is what they would experience in the wild. However they apparently grow up faster if you skip it, and I believe John Brittacher on the ICPS website [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]

    Yeah, the only reason is so the plants grow a little quicker, get mature quicker.

    hmmm..interesting,
    thanks Alvin!

    here are the 2 pages where John Brittnacher talks about letting the seedlings go 2 years without dormancy:

    http://epm-britt.ucdavis.edu/Savages/SarSeed.htm

    http://www.carnivorousplants.org/see...Sarracenia.htm

    but I still dont know why the seedlings dont need dormancy for 2 years!
    I guess the answer is "because they dont" [img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img]
    well, apparently it really works.. I wont complain!

    I am growing Sarr seedlings this fall, they are busy stratifying right now..so basically I will let them grow all of 2004 and 2005, and let them go dormant in the autumn of 2005, approx 2 years from now...I just wanted some conformation that this 2 year concept is real..
    update in 2 years then! [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img]

    Maybe it's the fact that there isn't enough of a plant there yet to require dormancy. For any dormancy to succeed at all would require stored energy of some sort. As far as seedling Dionaea and Sarracenia, I don't think there's actually what would be considered a rhizome developed yet. The plants still working on growing and establishing itself so that it can survive. Skipping the dormancy for those first two years which does not seem to harm the little guys, gives them more of a fighting chance. They don't have to deal with fungus and mold, or a million other things that could happen during a natural dormancy, and they can continue to grow to build up any sort of resistance to those threats.

    After those two years it has also increased the size of the rhizome and finished forming all that it needs to survive. I'm sure sarracenia have been known to start dividing themselves here and there after two or three years from seed, but before that i'm doubtful. I've even seen Dionaea seedlings that after two years started developing into dense clumps, but not prior.

    I had heard of the two year theroy as well and I found friends of mine that had grown sarracenias and they did this with great sucess to 'hurry' the plants along. I personally grew seedlings through last winter and on into this summer with no adverse effects. I plan on bringing 100s of 9 month old seedlings in this winter to keep them going. I will report back to you. Here is a photo of one of the seedlings that went through last winter. It took off this summer when it got hot. Notice the multi breaks in the rhizome already.

    Now Brooks, show them a pic of the plants that stayed out for the winter so that they can appreciate the difference not giving a dormancy makes [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]
