Pancratium illyricum, also known by the names of sea lily, Pancrazio and marine narcissus, is a spontaneous plant belonging to the Amaryllidaceae family. It has a tunicate bulb with dimensions between 16 and 20 cm and has flowers with a double corolla similar to narcissus but much more elegant. It has long ribbon-like leaves with a bright green color. It blooms in the middle of summer, with a very pure white. Pancrazio has Mediterranean origins: in Italy it grows easily along the coastal strips. The fruit of the plant appears as a large capsule containing black colored seeds. The flower of the sea lily is umbrella-shaped. It is white in color with green streaks. It is particularly fragrant and blooms during the summer. The height of the plant is about 60 cm. The leaves are green.
The cultivation of pancratium illyricum is quite simple. In fact, thanks to its resistance it adapts perfectly to cultivation in the open ground. If grown in the garden it can create beautiful round cushions. If grown in pots, it will tend to have smaller dimensions. As for the exposure, it prefers very bright and sunny areas. It needs hot summer seasons to show its splendid flowering. If the summer is rather cool, the flowers will appear but in a decidedly reduced number. It can withstand temperatures even below 0 °. Watering should be done only when the soil has been completely dry for several days.
