Acorus gramineus
Also called Dwarf Sedge, Japanese Rush, Japanese Sweet Flag, Grassy-Leaved Sweet Flag, Japanese Sweetflag, Slender Sweet Flag, Grass Leaf Sweet Flag
Grassleaf sweet flag is a grass-like perennial from wetlands in East Asia, grown mostly for its narrow leaves and used around ponds, bog gardens and aquariums. Keep its roots moist or submerged and it spreads readily by rhizome.
Acorus gramineus, commonly known as Japanese sweet flag, Japanese rush, grassy-leaved sweet flag, and grass-leaf sweet flag, is a botanical species belonging to the genus Acorus, native to Japan, Korea, and eastern Asia. The plant usually grows in wetlands and shallow water.
The genome of A. gramineus has been published by independent research groups in 2022 and 2023.
Acorus gramineus spreads aggressively by rhizome, creating a nearly-seamless groundcover where conditions are favorable, and it is frequently used around the edges of ponds and water gardens, as well as submerged in freshwater aquaria. It can be propagated by dividing the fleshy underwater rhizome and planting the base in shallow water.
