Hi Connie, thanks for the response.
I googled L. columbianum and is sure looks like that one.
I'm good with many plants, alas lilies are not one of them,
so I'm just guessing. I see them in the Big Sur part of the
California Coast and (I think) I see the same ones in the
Sierra Nevadas. They are almost always in a riparian area.
Silly Me, I'm surely answering my own question about where
they can grow. (Don't tell, but I have collected a few seed....
Plant OCD, I'm working on it) I just have this vision of some
sort of tall, native lily growing happily under my Coastal Live
Oak trees near my home. What do you think, is there help for me?
Thanks again, Lori
