Description: Bulbous perennial with a long neck and glaucous, broadly linear leaves, evergreen, but the leaves often die back during hot summers. Scape to 40 centimetres (16 in). Flowers 3–15 in an umbel, up to 15 cm (6 in) long, white. Corona two-thirds as long as the tepals. The flowers have a pleasing, exotic and very subtle lily scent, which only becomes apparent during still, windless summer nights that allow the delicate fragrance to become perceptible.
Biology: The flowering is from June to October, according the location.
The plant is pollinated by a hawk-moth named Agrius convolvuli. These insects visit the flower when the speed of the wind is under 2 metres per second (6.6 ft/s). When it’s higher than that, the moths does not visit the Pancratium plant. Even if the species is pollinated in an artificial way during windy weather the pollination is not effective. Another specific of the sand lily is that it is not receptive to its own pollen and the plant can recognize it. This flower can be only cross-pollinated.
Seeds are thickened, mostly due to the spongy outer layer which helps them float on water and dispersed by the wind.
Habitat: It grows on coastal sands or just above the high tide mark.
Distribution: Mediterranean region and south-western Europe. That plant can also be seen on the south Bulgarian and north Turkish coasts of Black Sea, where it is threatened with extinction.
