Species:superbum

Family:Liliaceae

The Turk's-cap Lily is a perennial wildflower that thrives in partial shade, reaching heights of 4 to 8 feet during the summer. It flourishes in deep, fertile, and moist soil found near cove forests, ravines, swamps, and coastal bogs. The plant features whorled leaves along its stem, and its striking orange-red flowers are adorned with purple spots. The six perianth segments curve backward, often touching at the tips. This species is particularly attractive to pollinators, including hummingbirds and butterflies, making it one of the easiest native lilies to cultivate in North Carolina.

Ideal growing conditions include humus-rich, moist to wet, yet well-drained soils, with exposure to full sun or partial shade. While it prefers these conditions, it can also adapt to average garden soil as long as it remains consistently moist. When planting, bury the bulb 5 to 6 inches deep and apply mulch to retain soil moisture. This lily is perfect for mass plantings around ponds or bogs, in rain gardens, naturalized areas, or as part of pollinator and native plant gardens.
