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. In a message dated 3/29/2013 5:48:40 A.M.

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://cites.com/ http://bulbs.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.
