This is a beautiful ornamental grass that keeps it's dramatic color here in central SC throughout most of winter. The color reminds me of the silvery blue color of Bismarck palms. I planted mine with setcreasea purpurea and orange coreopsis for a beautiful, dramatic effect. Protect from ground voles.
