Family

Cyperaceae

Botanical Name

CAREX siderosticha 'Spring Snow' ('Kisokaido')

Plant Common Name

Variegated Broadleaved Sedge

General Description

The broad, variegated blades of this showy, clump-forming sedge are ivory with thin, irregular green edges. This elegant Japanese introduction adds interest to shady perennial gardens and spreads over time to make a fine deciduous groundcover.

The arching blades of this variegated broadleaved sedge are bright ivory with deep green edges unlike the better known 'Variegata' which has green blades with thin ivory edges. In spring, inconspicuous grass-like flowers are produced which offer little to no visual interest. The leaves are fully herbaceous and offer no winter interest whatsoever.

Broadleaved sedge naturally inhabits the montane forests of Asia, so it grows best in partial shade and tolerates almost any evenly moist, fertile soil with good drainage. Full sun will cause leaf burn, even with regular watering, so be sure to provide this sedge some shade.

Variegated broadleaved sedge is beautiful in containers, looks great massed as a groundcover and compliments many other showy ornamentals for shade. Some good perennial partners include colorful large-leaved hostas, heucheras, upright ferns and tall astilbes. This vigorous sedge may be slow to leaf out in the spring, so don't be worried if it lags behind its other perennial compatriots.
