The plant is widely distributed in much of Canada from British Columbia to Quebec, and parts of the United States (Northeast and Great Lakes regions plus the Rocky and Appalachian Mountains).

[7] Lilium philadelphicum is listed as an endangered species in Maryland, New Mexico, Tennessee and North Carolina.

[10][9] Cats are extremely sensitive to lily toxicity and ingestion is often fatal.

[16] Rapid treatment with activated charcoal and/or induced vomiting can reduce the amount of toxin absorbed (this is time-sensitive so in some cases, vets may advise doing it at home), and large amounts of fluid by IV can reduce damage to kidneys to increase the chances of survival.
