Hymenocallis : Greenhouse Plants

Family: Amatyllidaceae

These bulbs are frequently listed in seed catalogues as Ismene. They are well worth investing in. Bulbs should be potted between November and January so that the neck of the bulb is just above the surface. The temperature they are grown at can vary between frost free and warm; the warmer they are the earlier they will flower. The flowers are quite spectacular, being shaped rather along the lines of a Daffodil but with the petals (correctly called the perianth tube) divided into curling segments. Most of the flowers are white and highly scented. Hymenocallis amanceas from Chile and Peru, H. X festalis of garden origin and H. X macrostephana are the ones most usually seen. After flowering, which takes place between April and June, they should be gradually allowed to die down, dried off and stored in a frost free place until the following year. Change the soil every two years otherwise top dressing is adequate.
