Laura (and others),
I'm late to the discussion due to craziness going on, but wanted to add that Siloam Peony Display does indeed have white seeds.
I had not heard of this, and thought that something was wrong when I collected from the first pod. Then the second and third pods also had white seeds. Most of them look normal, except for their coloring. They are about to go into the fridge, then I plan to germinate them. I will update as time goes by if I am successful in germinating them.
I have Moonlight Orchid also, but it did not bloom this year. Now I'm really looking forward to pollinating it next year
