Zephyranthes treatiae, commonly known as Rain Lily, Zephyr Lily, or Fairy Lily, is a perennial herb native to the Southeastern United States, particularly thriving in open woodlands, grassy areas, and along stream banks. It is often found in moist meadows and forest openings, usually on clay soils. This species grows at a moderate rate to a height and width of 0.5-1 feet (0.15-0.3 meters). The Rain Lily features narrow, grass-like leaves and produces white, showy flowers with six petals that bloom in response to rain during the summer and fall, creating a striking display in the garden.

The Rain Lily is valued for its ability to naturalize and provide bursts of color after rainfall. It is ideal for mass plantings in borders, rock gardens, and as a ground cover. It is also suitable for container gardening and can be used in water-wise landscapes due to its adaptability to wet conditions. While it prefers full sun or part shade, it is adaptable to a range of light conditions. The plant thrives in medium draining loam or clay soils and requires medium amounts of water, mimicking its natural habitat’s moisture levels. It is relatively low maintenance, but gardeners should be aware of potential bulb rot if the soil is too wet.CC BY-SA 4.0
