This was blooming in May and I am guessing it is a bulb.
Strap like leaves
It was in an open garden and the only one of it's kind.
(Zone 5) about 10 inches tall, flowers 1''
garden gus, I know you marked this closed but would you check out Leucocrinum montanum (sand lily, star lily)? I lived in Wyoming for awhile and this looks just like the pretty sand lily wild flower we had there.
Thanks for pointing me to that very interesting flower I always like learning about new plants. I do see the similarity in looks . Did some reading and the sand lily does not have a stem so I think that rules it out .
