'Evergold' Carex (Carex oshimensis 'Evergold') is a sedge plant native to Japan that likes wet-to-medium-wet soil and part shade. Its cream-and-green colors are more intense in the shade, but full shade can send the plant into decline. Growing to a foot tall and 1 1/2 feet wide, its compact habit makes it an eyecatching winner at the front of the border. In May, it bears brown flowers.
