Zephyranthes atamasca, commonly known as Atamasco Lily or Rain Lily, is a perennial bulbous plant native to moist meadows, savannas, and flatwoods, as well as the edges of marshes and other wetlands in the southeastern United States, from Florida to Maryland and west to Mississippi. It typically grows to a height of 6-12 inches (15-30 cm) with a similar spread. The Atamasco Lily is characterized by its glossy, narrow, linear basal leaves and showy, solitary white flowers that bloom in the spring, usually after heavy rains, hence the name "Rain Lily." The flowers are trumpet-shaped and can add a delicate beauty to garden settings.

The Atamasco Lily is valued for its low maintenance and ability to naturalize in appropriate conditions. It is often used in rain gardens, borders, and naturalized areas where its striking white blooms can be appreciated. It thrives in partial shade to full sun and prefers moist, well-drained, acidic soils. While the plant is generally pest-free, it can be susceptible to bulb rot if overwatered or planted in poorly drained soils. It is important to note that both the leaves and bulbs are toxic if ingested. Despite its poisonous parts, the Atamasco Lily is not typically associated with aggressive roots or other significant problems in the garden.CC BY-SA 4.0
