The "tall" in the seedling comes from Prawn Tiger. Lilium maculatum is very short, usually 1.5-2ft (46-60cm). The strength of the stem comes from Prawn Tiger, also.
I think that other one also came from the same cross, but I can't be sure. None of my seedlings looked at all like that, but when you look at the parents, it would seem very likely. Often I hear stories from breeders about how there was just one seedling that was very different from the rest in the same cross. And that one is
way better than anything I grew. Lucky you!
Prawn Tiger and L. maculatum var. wilsonii
We always like to see the results from seeds we distribute; thanks so much for showing them.
