The Carex oshimensis ‘Evergold’ is a genus from the sedge family (Cyperaceae) and is commonly named Japanese sedge or evergold sedge. The evergold sedge is originally found in dry, wooded areas and on rocky slopes in Japan.
The leaves are very sturdy, green and yellow striped, with sharp edges, and remain evergreen in winter. 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 full sun, it needs a moistier 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 the winter.
The Carex oshimensis ‘Evergold’ forms increasingly wider clumps. If the clump becomes too large, you can dig it up and divide it.
The evergold sedge is well-suited for use in rock gardens, as edging along paths and as groundcover.
