Rain lily

Zephyranthes reginae

zef-er-AN-theez REE-jin-ay

These Mexican native bulbs actually offer demanding gardeners flowers on demand. They produce strappy foliage to 12 inches tall and clusters of buttery-yellow, starry, crocus-like blossoms two to three days after every rain in summer and early autumn. Or, if it doesn't rain, simply water and fertilize three days prior to your intended display, and the moisture will prompt the flowers to appear, hence the common name, rainflower. These bulbs are widely adaptable to diverse soil conditions, and may be grown in full sun to partial shade, but they prefer some shade.

Noteworthy CharacteristicsThey are perfect for rock gardens, border edges, or for naturalizing. Where not hardy, they can be grown indoors in a cool greenhouse, or placed outside in containers for summer display.

CareProvide moist, well drained soil in full sun or partial shade. Avoid excess winter moisture. Adaptable to a wide range of soils.

PropagationSow seed when fresh; separate bulbs in spring.
