Hakonechloa macra 'Naomi' is a lovely decisuous / semi ever green grass with arching leaves that have yellow and green stripes.  It is a great grass for bringing autumn colour into your garden or pots as it turns reddish / purple during the season.  It doesn't get too big, so can also work well in containers.  Looks great when planted enmasse in drifts or large clumps. While it is slow to grow, it is a very tough grass.  Great for ground cover.
