Ismene, or Peruvian daffodil, is a genus of South American plants in the Amaryllis family.[3] The species are native to Peru and Ecuador and widely cultivated elsewhere as ornamentals because of their large, showy flowers.[4][5]

Ismene produces tender perennial bulbs bearing a strong resemblance to those of Hymenocallis, a genus into which Ismene had often been grouped in the past. However, its morphology differs from Hymenocallis in several significant ways: its vegetation, natural range, and chromosome number are all distinct.

Ismene can be difficult to grow in the United States.[6]
