    Stiff, upright blades of green turn metallic blue and then warm pecan brown in the fall. We are fond of this dynamic, vertical accenting grass in drifts with Teucrium fruticans 'Azureum'.

    A beautiful sturdy upright clump-forming grass. Steel blue foliage and panicles of burgundy tinted seed heads in September pair wonderfully with Sedums and Asters. 4-5' tall.

    Young glaucous blue blades mature to a shiny, metallic blue, extending vertically from dense blue stems. When in bloom it becomes one of the most delicate of the grasses. Feathery red inflorescences, gradually fade to silver and reach to 16" above the dense foliage. Fall color is bright yellow.
