Pitkin Marsh lily is a perennial herb that grows three to six feet tall with large flowers that are red on the outside and become yellow with maroon dots at the center. It flowers from June to July and is distinguished from the subspecies L. pardalinum ssp. pardalinum by its shorter petals and anthers. Pitkin Marsh lily only grows in permanently saturated, sandy soils at the edges of marsh wetlands and riparian habitat. Pitkin Marsh lily is also listed as endangered under the federal Endangered Species Act(opens in new tab). The largest threat to the survival of Pitkin Marsh lily is loss and disturbance of habitat resulting from nearby residential development. (link added by Mary Ann Machi)
