Rain lily Leaves are a deep glossy green and measure 3 mm wide. Flowers, which at first resemble a new leaf, but emerge from their papery sheaves to a stunning whiteness; they are erect in perianth.
Zephyranthes can be deciduous or evergreen bulbous perennials, with linear leaves and funnel-shaped or crocus-like flowers in spring, summer or autumn.
Robusta Rain Lily is a hardy perennial , will form clumps to about 25 cm tall and wide of glossy, narrow green leaves. Pink Rain Lily are large flowers that are rose in color with a white base. The flowers are much larger then that of Rosea Rain Lily, and the throat is distinctly white with six petals and yellow stamens, bloom on stems that are as tall as the foliage, will appear during rainy season or following an increase in moisture or humidity.
Zephyranthes plants generally produce three upright petals and three identical sepals, ranging from narrow to broad. The foliage is grassy and bright green, and tends to have a prostrate habit: think of the narrow foliage of grape hyacinth bulbs, which is similar. An individual flower will only last a few days, with the heaviest flush of blooms occurring first. The bulbs may bloom occasionally throughout the rest of the season, especially after heavy rain.
