The Carex oshimensis ‘Evergold’ is a genus from the Cyperaceae family and is commonly named Japanese sedge or evergold sedge. The evergold sedge is native to dry forested areas and rocky slopes in Japan.
The leaves are sturdy, green/yellow striped with sharp edges and evergreen. The flowers spikes are inconspicuous and do not have ornamental value as far as I’m concerned. Do not cut away the withered and ugly leaves until spring because the leaves protect the plant against frost.
Although the Carex oshimensis ‘Evergold’ may look like an ornamental grass it is not a grass.
The Carex oshimensis ‘Evergold’ is reasonably tolerant to salt and drought. If the Evergold sedge is positioned in the sun it needs more moist in the soil. In part shade this sedge can better tolerate dryness and the foliage colour is richer. It is important that the soil is well-drained. Especially in winter.
The Carex oshimensis ‘Evergold’ spreads gradually by short rhizomes. If the clump becomes too wide you can dig it up and divide it.
The evergold sedge can be used in rock gardens, as edging plant for paths and as groundcover.
