Cooperia is a genus of tender herbaceous perennials native to South America and the southern reaches of North America. They are closely related to Zephyranthes and Habranthus, all members of the Amaryllidaceae, or Amaryllis family. All three genera are commonly known as rainlilies because of their propensity for blooming after a rain. Cooperia blooms in summer and fall.
