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 vegetative parts, natural range, and chromosome number are all distinct.
Ismene can be difficult to grow in the United States.[6]
