State Rank Reason (see State Rank above)
Lilium philadelphicum has a patchy, but wide distribution in Montana, and is often found in specialized habitats. Observations in eastern Montana have not been made since the 1930's and 1940's. This species is vulnerable to extirpation in Montana because of its attractiveness, potential to be over-collected, and habitat requirements. Native lilies have rarely survived in gardens. Current information on known locations, especially in the eastern counties, is greatly needed.
