I'm assuming that Hsinying Franz is a multifloral. Brachys are known for knocking the flower count down when breed to multis. One exception is concolor X kolopakingii, i get typically 4 flowers and Robert has a clone that blooms with 7. The brachy flower will be elongated by most multis.
That's the best I can tell you
BTW Eric! super buy! that is very nice. Is there any other buds?
