Description and Ethnobotany
| Growth Form | It is a compact, perennial herbaceous plant, growing up to 0.3 m tall and about 0.8 m wide. It produces offshoots at the base of the plant, creating a crowded appearance. |
|---|---|
| Roots | The fibrous roots are fleshy. |
| Foliage | The leaves are long, narrow (about 74 cm long × 1.2 cm wide), narrowly lanceolate, arching and variegated with a thick white marginal band and a central green band. The variegation at the base of the leaves is greener than that on leaves exposed to the sun. The leaves are arranged spirally in a rosette. The leaf margins and underside of the midribs are armed with numerous hooked spines. |
| Flowers | Flowers have not been observed in Singapore. |
| Taxonomy | This hybrid was selected by Bart Noordhuis and Elisabeth Bisschop of External Plants in Bojil, the Netherlands, and often marketed in the horticulture trade as Carex Feather Falls™ or Carex 'Feather Falls'. |
| Cultivation | It grows best in fertile, moist, well-draining soil, in full sun or semi-shade, with little to moderate watering. It is tolerant of temporary waterlogging; prolonged waterlogging can lead to root rot. Established plants are drought-tolerant. It can be propagated by division. |
| Etymology | The genus Carex is derived from the classical Latin name for a sedge. |
