The exotic white flowers have extremely long, hanging petals with a central staminal cup formed from the membranes of the staminodes.
The name Hymenocallis means ‘beautiful membrane’. With long strappy leaves, most plants resemble agapanthus when not in flower. Unlike agapanthus, they have a long flowering period and at times are so smothered in flowers you can hardly see the foliage. The biggest flush of flowers occurs at the start of the rainy season and then the flowers seem to come in flushes coinciding with very wet periods. Flowers open in the evening emitting their perfume overnight and generally last 2 to 3 days.
