Hi Rick, I do grow Lilium chalcedonicum successful since nearly 10 years in Bonn in Germany. It is in my expierience a difficult lilie anyway. It is only one spot in the garden where it grows well. All other places do not work propper. I will harvest a lot of seeds soon and I have seedlings. I am not sure if I can send plants to the US, but seeds will be no problem as soon as they are ripe. I never did any breeding. I am most interessed in wild plants! Michael Neumann
