Although a monotypic (only containing one species) genus, this is an indispensable Japanese grass, for a shadier spot, or one with reasonable moisture. Hakone  grass (named after a mountainous area south west of the Tokyo megalopolis) is deciduous, with stems are arching and small sprays of fine flowers. The various forms of foliage, green to yellow and variegated, are a highlight, with over 20 cultivated forms available in the UK. When settled and making a low rounded mound, a little wind rippling through them is quite a sight.
