Acorus gramineus ‘Ogon’, also known as golden sweet flag, is a striking, low-growing perennial valued for its vibrant, sword-like leaves streaked with bright gold and green. This moisture-loving plant forms dense, clumping tufts that bring a splash of color and texture to the edges of ponds, bog gardens, or shaded borders. Its foliage gives off a light, pleasant fragrance when crushed, and remains attractive throughout the year in mild climates. ‘Ogon’ thrives in wet or consistently damp soils, tolerates partial to full shade, and adds a luminous, almost glowing effect to any garden space, especially when planted in masses or used as a ground cover.
