Ismene narcissiflora

Ismene was classified in 1892 in the genus Hymenocallis, part of the family Amaryllidaceae, but since 1990 it has been classified as a separate group because of botanical and genetic differences.

The main difference is that the leaves of Ismene form a pseudo-stem. The flowers are declinate to pendulous, the staminal cup is usually ribbed green.

The flowers are usually white and very fragrant but there are hybrids of different colours and they give an exotic touch to the garden.
