Carex oshimensis ‘Evergold’ is a grassy, evergreen sedge with long golden leaves, each with deep green margins. It makes a graceful, arching clump that doesn’t spread. It’s ideal for growing in perennial container displays as a foil for brightly coloured flowers, and also looks good planted beside ponds or at the edge of borders. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM). Clumps to 45x45cm.
