Physical description: This plant has a grass-like habit and forms a
dense, compact tuft. It may reach 12 in. or more in height in
very fertile soil, and 12 to 18 in. wide. The semi-evergreen
leaves are flat, thick, and reach 12 in. long and ¼ in.
wide. They are dark green with narrow white edges. Flowering
occurs in early to mid-spring, and the brown, short-lived flowers
are clustered in groups of four to six. It is important to note
that flowers are non-ornamental.
Optimal growing conditions: Japanese sedge performs best in shade; this unusual
trait is not common for true ornamental grasses. It does well
in organically rich soils with high fertility, but is not very
drought tolerant; watering during the summer can be useful. Winter
hardiness: Zones 6 to 9.
Susceptibility to pests and diseases: Japanese sedge has no serious disease or insect
problems.
Use:
This ornamental grass is a good selection for the front of shade
borders or shady rock gardens.
