Plant Profile: Zephyranthes atamasco

Rain Lily, a perennial bulb resembling an onion, is indigenous to the southeastern United States, particularly thriving in the coastal and Piedmont regions of North Carolina. Its grass-like foliage can often go unnoticed when not in bloom. However, in spring, it showcases striking, fragrant trumpet-shaped flowers that are predominantly white, occasionally featuring a hint of pink. This plant can propagate through bulb offsets, leading to the formation of colonies, and it enters a dormant phase during the summer months. Notably, Rain Lily was honored as the 2010 Wildflower of the Year in North Carolina.

This resilient plant flourishes in rich, moist to wet, yet well-drained acidic soil, thriving in conditions ranging from full sun to partial shade. It benefits from the addition of leaf mold to enhance soil quality.

The designation of Wildflower of the Year in 2010 was part of a program overseen by the North Carolina Botanical Garden, with financial backing from the Garden Club of North Carolina.

In terms of habitat, Rain Lily is commonly found in bottomland forests, along road shoulders, in wet meadows, and occasionally in upland forests situated over mafic rock formations.
