    Huh...interesting read there NaN. Since your belezeana is a natural hyrbid does it require dormancy unlike "Ivans paddle?"

    I have a flowering D. belezeana "nightmare". Just started unfurling the stalks (2). Should have some flowers shortly. I was going to try growing without dormany (since I'm going to get some seed), but was told it needs it.

    Yes, they are from the NJ Pine Barrens and needs dormancy. In fact it already has formed the winter bud since July when I took the picture. This is typical of other Drosera from the Pine Barrens in my collection. They'll go into the fridge in a couple of weeks.

    If you made your own D. x belezeana by crossing D. rotundifolia 'Charles Darwin' and D. intermedia "Cuba" you could end up with plants not requiring dormancy.

    D. belezeana is not fertile unless "spliced" with Colchicine to make them tetraploid. You might get seed but otherwise they shouldn't be viable.

    Ivan said the stuff obtained from medical tablets didn't seem potent enough to be effective but fortunately one of his contacts had some of the reagent grade stuff left over.

    Tamlin, Ivan has registered the D. x obovata as a cultivar 'Ivan's Paddle'. While it is a fertile diploid he says the seed offspring are usually so weak they are not worth cultivating. Dr. Frankensnyder has plenty of other horrors waiting to be unleashed from the lab.

    Colchicine is still available -- albeit at somewhat elevated prices, both for the material and the hazardous material shipping -- through tissue culture suppliers, such as Phytotech:

    Thanks for the info, I'll pass it on to Ivan for when his source dries up.

    Yes, I was aware that Ivan registered D. 'Ivan's Paddle' but there are soooo many more!

    True, he did have quite a few siblings of 'Ivan's Paddle' that he gave away because he couldn't get them to flower. He gave away his D. capillaris x rotundifolia for that reason but you can still find those for sale in a couple nurseries.

    And this is the second time he's made D. x tokaiensis.
