Acorus gramineus 'Ogon', commonly known as Golden sweet flag, is a low-growing, clump-forming marginal perennial with narrow, arching golden-yellow leaves that create striking groundcover along pond edges and in moist borders. It produces inconspicuous flowers in summer, while its vibrant foliage provides year-round ornamental interest and a bright accent in water gardens.
This cultivar thrives in shallow water or consistently moist soil and supports wetland insects. Its spreading habit and tolerance of waterlogged conditions make it ideal for pond margins, bog gardens, and naturalistic planting schemes where low, bright foliage is desired.
