Thank you for your explanations, Rick.
Based upon them, I would say the white martagon Lily must be 'that one different in the batch' from your 'Claude Shride' seeds
Prawn Tiger and L. maculatum var. wilsonii look like the perfect parents of my Lily NN. Do you want to name it? I want to add that this Lily is quite a prolific bulblet producer. On the other hand, they are not great spontaneous (OP) seed producers. I have had only a few seed pods, containing mainly .... chaffe.
I'm not sure and tend to think that the two salmon/orange Lilies proceed from the same cross, because they were sowed (or is it sown?) in different seed trays. When I re-planted them, there were originally some 8 seedlings of Nbr. 4, clearly all the same characteristics, and the 200+ of the pictures above (Lily NN) have all the same characteristics as well - no mixes of the two of them.
I love Lily World and this Lily Forum!
