Description
Description

Japanese Sedge (Carex oshimensis), commonly known as Oshima Sedge, is a refined ornamental grass native to Japan, particularly the island of Honshu. Belonging to the Cyperaceae family, it is not a true grass but mimics the form with narrow, arching blades that grow in dense, mounded clumps. It is often used in landscaping for its graceful texture and evergreen foliage, maintaining visual interest throughout the year in temperate regions.

This sedge naturally grows in shaded woodlands, moist slopes, and rocky clearings, where it plays a role in stabilizing soil and softening understory vegetation. It spreads modestly by rhizomes, making it well-behaved and ideal for borders, mass plantings, and containers.

Known for cultivars like ‘Evergold’ with striking variegated leaves, Carex oshimensis stands out for its versatility and visual delicacy. Its ability to thrive in low-light settings and its tidy form make it a favorite in modern gardens, Japanese landscapes, and naturalistic designs.
