This is Lilium superbum, also known as Turks Cap Lily, turban lily, swamp lily, lily royal, American tiger lily and American Turkscap Lily. This beautiful lily is happy to live in the full sun or all the way down to light shade. They bloom from late Summer until early Fall. This plant is native from New Hampshire down to Florida and as far west as Missouri. The colors have a range from bright yellow to orange-red to red at the petal tips. This effect looks like a flame burning. This is one of the most gorgeous flowers anywhere and that is why it was named superbum. It puts on a beautiful display. These American Lilies have a green star in the center of the blossom. This is the distinguishing feature that separates the American Lily from the other Asiatic Tiger lilies. This was also a food source for Native Americans. Not only the people, but the bees, butterflies and hummingbirds nectar on this plant. The bulbs are slightly sweet and starchy. They can be cooked and eaten in place of a potato. or the bulb can be used as a thickener. This plant is endangered in Florida and New Hampshire. I will consider a photo of a butterfly nectaring as evidence that that butterfly uses this plant as a nectar source. Therefore this plant is a nectar source for the Monarch, Black Swallowtail, Spicebush Swallowtail, Eastern Tiger Swallowtail, and Pipevine Swallowtail butterflies. USDA Hardiness Zones 4 to 9.
