I was looking back through a couple of notes. WORTHY OF DISTINCTION has been a difficult pod parent for me. It will set, and I've done it, but usually once a season. MIDNIGHT MYSTERY is an old wine/near black that I really love and it just aborts any and everything you put on it.
I've had LARRY'S TWILIGHT BITE since it was introduced and it is difficult but this year finally set a single pod. With a single seed.
It's readily pollen fertile though.
The last one is SILOAM GOLIATH. An enormous dinner plate of a bloom on big thick scapes. It very reluctantly will set a pod but they are often empty. The stamen are often kinked at the end and pinched as if they ran out of room to grow.
