Lilium washingtonianum

Lilium washingtonianum is a North American plant species in the lily family.[1][2][3] It is also known as the Washington lily, Shasta lily, or Mt. Hood lily. It is named after Martha Washington[2] and not the state of Washington; in fact, as the northern range of the plant is near Mount Hood in Oregon, it does not naturally occur in the state of Washington.
