Golden Variegated Sweet Flag (GVSF) is a grass-like, evergreen perennial that has pale green narrow leaves with a vertical white strip. Unlike the common mondo grass and liriope, GVSF can withstand constantly damp to wet soil or be slightly submerged at the edge of a bog, pond or stream.

Plant GVSF in full sun to moderate shade. When planted in full sun, it should be in soil that remains reliably damp or the foliage may scorch. The soil should be acidic in pH and high in organic matter. Remove any tattered foliage in the early spring just before new growth begins. Divide every few years in the spring. Deer resistant.

GVSF makes a wonderful companion plant with other bog or stream plants. When growing in full sun, good companion plants include: Pickerel Weed, Redtwig Dogwood, Pitcher Plants and Japanese Iris. In shade, plant GVSF with: Lady Fern (and Foam Flower), Hosta and Cinnamon Fern.
