Rain lily (Habranthus robustus)
Synonyms:  Zephyranthes robusta
Genus:  Habranthus
Pale pink flowers pop up suddenly after a summer rainstorm and resemble small amaryllis flowers on this native of Brazil. In the proper conditions, they can multiply rapidly and carpet the garden.
Noteworthy Characteristics:  This robust perennial is suited for southern gardens or greenhouse use, with attractive flowers held above the foliage.
Care:  Under glass, plant bulbs 3 to 4 inches deep, in soil-based potting mix with added grit and leaf mold, in full light. Water moderately as growth begins, and then freely in leaf. Reduce water as foliage dies back, and keep barely moist when dormant. Fertilize weekly when in bud. Outdoors, plant bulbs in spring with the necks above the soil surface. Grow in fertile, well-drained, neutral to alkaline soil in full sun. Protect from excessive winter moisture.
Propagation:  Sow seed at 61°F as soon as it is ripe. Remove offsets in winter and pot up separately.
Problems:  Infrequent.
