A low-growing perennial that forms fans of rich golden-yellow, grasslike tufts, 'Ogon' makes an excellent container subject or small-scale groundcover. In shady areas usually dominated by different shades of green, the golden foliage adds a delightful twist. Must have at least partial shade in inland gardens. Garden origin.

Evergreen can be a necessary thing. Being gold can be a provocative thing. 'Ogon' has both and is also tolerant of wet to average soil types. Growth to 1 ft tall and slowly spreading. Makes a perfect punctuation in the garden, good accent in a pot, or visually exciting in a sweeping swath.
