Hakonechloa–commonly called Japanese forest grass or Hakone grass–is a graceful, slender clump-forming perennial grass. It has arching stems that grow 18 inches 945cm) tall or more. A species called ‘Aureola’ is commonly grown; its leaves are bright yellow with narrow green stripes. There is a solid green species that is less often grown.
Hakonechloa has the effect of a tiny bamboo. It spreads slowly by underground runners. The loose, nodding leaves produce 3 to 5-flowered spikelets. Leaves can become red-flushed in autumn and that color can persist into winter.
Hakonechloa is a good choice for woodland or rock gardens or partially shady gardens or for close viewing in containers.
Hankonechloa is a genus of one species. It is native to wooded areas of Japan.
