Hakonechloa
''Hakonechloa macra'' (Japanese forest grass, Hakone grass) is a species of flowering plant in the family Poaceae, subfamily Arundinoideae, native to Japan. It is the only known species in the genus ''Hakonechloa''.〔〔Makino, Tomitarô ex Honda, Masaji. 1930. Journal of the Faculty of Science: University of Tokyo, Section 3, Botany 3: 113〕〔(Tropicos, ''Hakonechloa'' Makino ex Honda )〕
The various cultivars of ''Hakonechloa macra'' are used as foliage plants in gardens in temperate climates.
==Description==
It is a small, mostly shade-loving, clump-forming, slowly spreading plant. The stalks cascade in a graceful rounded fountain shape somewhat reminiscent of ''Pennisetum'' (fountain grass) but with the actual foliage resembling ''Chasmanthium'' (The flowers are NOT similar). These grasses are notable for their texture and their colors as well as their general ease of maintenance. The leaves are thin and papery and resemble many forms of bamboo. They are very flexible and have a distinctive rustling sound when the wind blows that adds to their appeal. The foliage rises from the roots on thin wiry stalks, and the flowers bloom in midsummer from leaf nodes near the ends of the stalks. The flowers are light purple fading to tan then dropping off over the course of several weeks. The leaf blades are green but many color variations exist. The papery texture keeps the foliage cool to the touch and often the surface is slightly puckered or rippled. The cultivars may be boldly variegated in stripes of white, green, or yellow, or have solid colored leaves. Some cultivars tend to turn orange or red in colder weather. The species tends to be between 45 cm and 60 cm (18" to 24") with cultivars often growing significantly shorter. The height may be somewhat dependent on soil moisture, nutrients, and length of growing season, though the plant is tough enough to survive in USDA Zone 5 (-20 °F). It prefers even moisture and average humidity but can tolerate minor dry spells, and arid climates with minimal damage.
