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: http://citesbulbs.myspecies.info/content/… 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!
