Congratulations, Michael!
I have never hand pollinated my Super Tsings, but I have had many pods develop. They could have been crossed with L. martagon or another L. tisingtauense cross, or, I suppose, they could have been apomictic. Sometimes the seeds were very thick with so much endosperm that they could not be candled. But that isn't necessarily a good thing. The one time that I seriously tried to rear offspring, the germination percentage was extremely poor.
