    Experiment?

    My D. burmannii is blooming and right next to it is the D. lanata I just received. I had just cut off the older stalk but left the younger one be. I can't remember ever a time that a sundew flower stalk ever bloomed, after having been shipped with the stalk. Trouble is, I have no other Petiolaris plant with a flower, much less a stalk. Maybe I could try hand-pollinating with the burmannii? They're both Aussie plants....

    There's no harm in trying. The toughest part is getting two flowers open at the same time and and same place and being there when it happens. That may mean taking the plants to work and having them in front of you at all times.

    See this article posted by Tamlin on Ivan Snyder's (aka Dr. Frankensnyder) method of cross pollination.

    You may have to treat with Colchicine to get compatible chromosome counts.

    After being asked for a good method for cross pollinating Drosera species, I wrote to friend Ivan who kindly provided this reply:

    Hi Tamlin,

    Here is a piece on Drosera Cross Pollination for the forum. Post it for me as I am not subscribed.
    Ivan

    Here is my best trick for cross pollinating Drosera. Others might just rub the flowers together and plant the seed and later sort out the seedlings. Using this trick 100% of the seedlings may be hybrids.

    First, get both flowers to open on the same day. As soon as they open use a needle point forceps to pluck off the stamens. As most flowers are small, use a magnifying lens, 5 or 10X works well. Then use a spray bottle to wash off pollen. Any water on the flower can be blotted off with tissue paper. Wash off the forceps. You can either use the forceps to pluck of the stamens from the other flower and touch them to the stigmas of the receiver, or just rub the flowers together. Check with your lens for pollen on the stigma. Tie a piece of thread to mark the flower, and make a note. After about a week you will see some swelling of the ovary if you
    were successfull.

    My latest hybrid is D. capillaris X rotundifolia. I don't think
    anyone's made it before. It proved to be sterile as anticipated. I mostly make hybrids just to see what will happen. I'm not really trying to create a nice new cultivar. Sometimes I learn something important to CP science.

    Perhaps my best example of this was in crossing D. burmannii
    with D. sessilifolia. This cross is completely fertile proving the
    close relation of these two.

    I had to put these two posts together to make it easier for me to follow. You'd think I'd know the parts by now!

    They are open at the same time. I'll give it a go since I don't have another Petiolaris plant with a flower. Coincidently, I have a D. sessilifolia blooming.

    Well, I just acquired a mature D. ordensis that had flowered some weeks before I got it. Unfortunately all the flowers are expired and no seed capsules formed. I should have jumped on Homer's D. ordensis seed give-away to have different genetic material to produce more seeds.

    Jim,

    That lanata that I sent you had a few more openings to go. My shipping must have been acceptable if your talking about the same plant. I wanted to cross-pollinate that plant myself but had no other lanata or petiolaris clones blooming at the time. Hope it works out for you. Keep us updated.

    Same plant, newer scape. White flowers. Tedius chore! That plant is doing fine. I put the smaller plant in another pot. It's still acclimating, so it doesn't have dew yet.
