My mother gave me these lilies three years ago, and I'd love to know what species they are. I figured someone would need to see the bloom to make an accurate identification, but haven't been able to get them to bloom.

I broke apart the root ball last year and replanted in a larger container. If I recall correctly, they didn't have bulbs, rather stringy roots. I placed them under a west-facing window in my bathroom. They are finally blooming, and I am so happy! Maybe now someone will be able to tell me what type of lily they are. Any thoughts?
