Sorry for delay, Larry. Very busy lately. I noticed the importance of using reliably fertile pollen on the first bloom on a scape by observing how pod-setting behavior progresses with my generally fertile pod parents. I don't remember where I first heard mention of this phenomenon. Maybe Oscie Whatley's writing? There was a reference to the idea that it's fruitful to get the scape "in the mood" for podding by pollinating the first blooms, even if that is just a selfed or throwaway cross. (Also, I see that the base of the first blooms is sometimes a bit thicker and looks like it wants to set a pod.) In my garden this happens even with mid and later-season bloomers, when it's hotter. It's not just that the first bloom opened before the summer became inferno-like. Maybe sometimes the scape just isn't in the mood, but I have seen a trend that once a pod is set, the scape seems invested in supporting it (and subsequent pods) and the opposite seems true. Scapes give up easily.
But whose pollen do you use to pollinate this cross? DL pollen is not equally fertile. Certain DL pollen will set a pod on just about anything. Velvet Throne is an example that has been discussed before. It's good to keep track of these easy pollen parents, given that the stakes are high.
Here's Diviner's Handbook last year. Was very much in the mood for procreation! And you can see Boy's Night Out on at least one of the tags.
