Acorus Gramineus 'Ogon' (Ogon Sweet Flag) is a striking ornamental grass with narrow, arching green leaves edged in bright yellow. It forms a dense, tufted clump, providing a bold splash of colour to ponds, water features, or garden borders. This variety thrives in moist, well-drained soil and is perfect for adding texture and contrast in landscaping.
Ogon Sweet Flag produces a subtle sweet fragrance when crushed and can tolerate both full sun and partial shade, making it an adaptable choice for Australian gardens. Its graceful foliage provides year-round interest, and it can also help prevent soil erosion near water features.
