Imperata cylindrica, Japanese blood grass, is such a variable species, depending on its habitat.  It has become an invasive noxious  weed in the U.S. southeast.  Not so here in our dry climate!  It is a warm season running grass, kept in check by limiting its  moisture.

Variety:

Imperata cylindrica 'Red Baron'     leaves green suffused with red, especially at the tips, with red increasing as the season progresses, 1' tall     zone 5     full sun, in moist fertile soil     does very well in containers
