Plant Description and Details

Bunchgrass extraordinaire, Idaho Fescue has artistic, fine blades of blue green, seemingly lightly coated with a whitish powder. It's forms a dense clump of striking-colored leaves and sends up delicate seed heads that wave in the breeze all summer.It will slowly self-seed if the seedheads are left to mature. It is an effective ground cover or alternative species for lawns. Selected varieties have been sold as ornamentals in the nursery trade, so it is a familiar landscape plant.
