Sylvain, have you seen the slide show by David Clulow? Here it is---

I do much the same thing, except that I try to be as gentle as possible to the flower, rather that chop it all to pieces as he does. I use an exacto knife to split two petals down to the bottom, that I cut off one of the ?? pointy things to free the stigma. Then once I have the pollen dumped in there, I use tiny thin strips of masking tape to put the flower back together. Huh?? Let me know if you try this. I also use a long deli-sandwich type toothpick to move the pollen. Chop off some of the point, and cut the end kind of flat to hold the pollen. Wet helps. Wind doesn't help. blows the pollen away, arghhh! And TAG each flower!! You WILL forget what you've done.
And, yes, Joanna, I still can't choose one single plant that I might sell, even though I have more than 200!!! I must start selling some. No, I don't ship to the USA, as a phyto-sanitary certificate is $65. ouch.
Went to a local nursery yesterday and--- bought an Adenium!!! $34 for a Siam Purple (single) to cross with Mike's double and triple purples. I am terminal!
