I am interested if all lilies go to seed. I had some in the garden last year and not one of them did.
but this year I have another 320 that are going to bloom
and another 100 or so to be planted yet........
maybe just leave one flower on the plant and see what happens....... I have 10 Regale's to be planted and they are actually specimen lilies from a seed....so they will for sure self seed I think and be true to themselves unless mother nature gets her hands in there although I read even if that happens you still get only Regale's.

I just wander if cross pollination by nature as per say is as popular as they seem to think it might be

also if you have a lily that just happened by nature would love to see it.........
