Acorus Golden Edge

Acorus gramineus ‘Golden Edge’ (Golden Japanese Sweet Flag)

Bring a year-round splash of luminous color to the damp, difficult spots in your landscape with *Acorus gramineus* ‘Golden Edge’. Though it looks like a delicate, variegated ornamental grass, this incredibly tough, semi-evergreen perennial is actually a wetland native. It features narrow, gracefully arching fans of bright mid-green leaves margined with striking golden-yellow stripes.

When bruised or crushed, the foliage releases a pleasant, sweet scent. Highly versatile, ‘Golden Edge’ is just as comfortable growing as a lush groundcover in damp garden beds as it is sitting directly in shallow pond waters.
