So many beauties! I could comment on every one.....
An upright trumpet seems so odd, just like an upfacing recurved lily. They just don't seem "right" to me.
But, they are interesting.
Øystein, it looks like the seed you received from John Lykkegaard is a mix of rosthornii/aurelian variations. To my eyes, only the one in the foreground has species characteristics. And even that one seems to be more L. henryi than L. rosthornii.
