Zephyranthes are commonly called rain lilies since they often come into bloom after it rains. From the Amaryllidaceae family, they are native to the southeastern United States, Central America, and South America. Most of the species are spring or summer flowering. A delightful effect can be produced by planting the species in the grass. The pink expanse of flowers looks fascinating. It is useful as a border plant in front of shrubs and can be used in window boxes, shallow pots or bowls.

Pale pink flowers pop up suddenly after a summer rainstorm and resemble small amaryllis flowers on this native of Brazil. This robust perennial has attractive flowers held above the foliage. This rain lily has earned its “robust” name by blooming for a long season, beginning in December and continuing on and off through to March. One of the most prolific of the summer flowering Zephyranthes, robusta produces large, clear pink blossoms that pop open on 20-30cm stalks that rise from slim, deep green foliage. This is a plant that asks for little, delivers dependably and should grace every warm weather garden.
