Just keep in mind, this is a future event. The plants are not producing currently, and I can't say for certain that they will. I have not cut by photoperiod back yet: I am experiencing the beauty of flowering Pinguicula, and if I go down much, all the rosettes will immediately go into winter dormant mode. They only start growing well for me in August, and are flowering in middle September. I am lucky to get one month of active plants! So this year, I am leaving the photoperiod extended, and this certainly will delay the gemmae. I feel confident enough that it will happen to get ready for the event, but it has not happened yet.
Also, as I said, I can't really promise any specific species. I will try to meet your requests if you care to make them, but there is no way I can fortell how much I will have, or if I will have it. Or if I will remember it, even if I said I would! Ya spins the wheel and ya takes yer chance. I hate to disappoint, so the less promised the better.
