Zephyranthes candida, with common names that include autumn zephyrlily, white windflower, white rain lily, and Peruvian swamp lily, is a species of rain lily native to South America including Argentina, Uruguay, Paraguay, and Brazil. The species is widely cultivated as an ornamental and reportedly naturalized in many places (South Africa, the Indian subcontinent, Zimbabwe, Seychelles, central and southern China, Korea, Nansei-shoto (Ryukyu Islands), Bhutan, Solomon Islands, Queensland, Nauru, Tonga, Society Islands, Mariana Islands, southeastern United States (from Texas to North Carolina), the Lesser Antilles, and Peru). Leaves are a deep glossy green and measure 3 mm wide . Flowers, which bud late in August (when propagated in the Northern Hemisphere) at first resemble a new leaf, but emerge from their papery sheaves to a stunning whiteness; they are erect in perianth white and sometimes pinkish abaxially. The leaf-like bract is 1.8 to 4 cm. They grow best in full sun to part shade and require a medium wet soil. Propagation is done by dividing bulbs or offsets and from seed.
