So Rick, did you ever try it as a pollen parent??????
I have tried it as a pollinator for a few years now on other Langkongese hybrids and this year I have one or 2 pods developing on those, but I moved them to shade and we are still having YO-YO weather so they have appreciated the cooler moments. (not as much as me!!!) Most of the time I get no seed here even on the easy ones, EXCEPT the Western American hybrids, they are VERY happy this year and I have started seed harvest, got more than I know what to do with, there may be some OP seed on the blooming auction this fall. The butterflies LOVED them! Probably hummingbirds and moths too.
This is one making a pod I think, not going out there to look now, it is hell on earth here today
