Dear Jim ,Thanks for your information. I am very familiar when you have a  
self sterility problem with certain flowers. As a retired grower once I  
know once other growers find a clone of something that grows well and has  some 
good qualities growers will just multiply that clone.The problem is losing  
genetic diversity. One disease can wipe out a susceptible clone and then it 
is  gone, maybe forever.-Russ H.

Another  possibility is that we are seeing one single clone making up the  
commercial stock of Sternbergia.  It is probably self-sterile, as  many 
other plants in the Amaryllidaceae are.  All you might need to  get seeds 
would be some live pollen from a different clone of the same  species.

Another problem is that S. lutea occurs as triploid (2n = 3x =  33) as well 
as the diploid (2n = 22) form.  Triploids are usually  sterile.   See:…

I  would guess that you will have to find seeds of the diploid form, from 
one  of the seed exchanges or from someone like the Archibalds.  Good  luck!
