Applications

The flowers of the Hymenocallis look more like a daffodil flower than a lily flower, this is why there are two different common names. The flowers have a long cup with projecting stamens. There are no leaves on the stem, and the flowers are fragrant. Hymenocallis is suited to growing outside in a sunny spot, but most often used in pots and containers.
