Plant Threat Level: 

Lilium catesbaei, or pine lily, is found in wet pine woods and savannas, especially in sphagnum moss pitcher plant bogs throughout the southeastern United States. The pine lily flowers from late summer into fall, depending on its location. There can be sporadic spring and fall flowering on plants found in the Florida peninsular. The pine lily's flower is the largest of any North American lily and one of the largest among our native monocots. The flower often dwarfs, and sometimes topples, the slender stem. Leaves are small and relatively few. It is primarily pollinated by an endemic swallowtail butterfly. The widespread alteration of native longleaf and slash pine savannas, in addition to sphagnum bogs, continues to threaten this lily. Conversion of its sensitive habitat to pine plantations and suppression of needed periodic forest fires contributes to the threats to this beautiful native plant.
