    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.

    Acorus is a member of the Aroid family, but with inconspicuous flowers, and is commonly known as Sweet Flag. The cultivar 'Ogon' has attractive iris-like foliage with pleasing cream and chartreuse variegation. It grows to 12" and loves wet soil, forming a handsome groundcover over time.

    This bold, semi-evergreen perennial has rich golden yellow foliage and grows to about 10" tall.

    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.
