Zephyranthes atamasco, commonly known as Atamasco Lily or Rain Lily, is a perennial herb native to moist meadows, flatwoods, savannas, and low-lying areas in the southeastern United States, extending 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 known for its striking white, funnel-shaped flowers that appear in March or April, with each bloom lasting just a few days. The flowers are quite showy, often emerging after rain, which is why it’s also called the Rain Lily. The plant has narrow, linear leaves that may remain attractive throughout the growing season if moisture is sufficient.

The Atamasco Lily is valued for its low maintenance and the beauty of its spring blooms. It is often used in naturalistic plantings, rain gardens, and as a border plant in residential gardens. It prefers acid, boggy soils and typically requires consistent moisture, although it can tolerate short periods of drought once established. It thrives in full sun to part shade. While the plant is generally pest-free, it can be susceptible to bulb rot if the soil is too wet during dormancy. The bulbs and leaves are poisonous if ingested, so care should be taken if planting in areas accessible to pets or children. Despite its toxicity, the Atamasco Lily is not considered invasive and is a charming addition to southeastern gardens.CC BY-SA 4.0
