The plant’s name is derived from polios (Greek for "pale") and anthos (Greek for "flower"). This genus includes a species known to have been cultivated for centuries as a cut flower: the Polianthes tuberosa. This species was also known to Clusius in the 16th century, and a double-flowering version became known in the 18th century. Most species are fragrant.
Applications: The bulbs are not entirely hardy and should thus be lifted in regions where long periods of frost occur. In warmer regions, the bulbs will reproduce themselves. In colder areas, they can also be planted easily in pots. Plant them 8 centimetres deep in a 20-centimetre pot or 15 to 20 centimetres deep in a 30-centimetre pot. The flowers are also perfect for cutting.
- Polianthes tuberosa: introduced in 1629, this plant has long been used to produce cut flowers. Its fragrant white flowers, opening up to 6 centimetres across, are borne on 90-centimetre stems. It most familiar cultivar, ‘The Pearl’, produces long-lasting flowers; the first to open eventually fall off while the rest of the buds continue to open, thus extending its flowering season.
- Polianthes gracilis: introduced in1879, this plant has narrow leaves and grows to a height of 40 centimetres. It produces white flowers with a waxy texture. Flowers are produced in late summer.
