Siskiyou Blue Idaho Fescue

Siskiyou Blue is a named selection of Idaho fescue grown for its fine, spruce-blue foliage and compact evergreen clump. The exact-selection listing from [High Country Gardens](https://www.highcountrygardens.com/products/perennial-fescue-grass-siskiyou-blue) gives a mature height of 15–16 inches, a spread of 15 inches, and growing zones 5–9. ## Landscape Use Use the narrow leaves as a cool-colored accent along a sunny border, in a mass planting, or in a container. The clump stays small enough for edging and compact gardens, while its late-spring flower spikes add a fine-textured vertical note. ## Growing Conditions Provide full sun or morning sun with afternoon shade. Plant in well-drained, low-fertility soil; the High Country Gardens listing describes its water use as low and its soil moisture preference as average. Avoid persistently wet ground. ## Seasonal Interest The blue foliage remains an evergreen feature, with upright tan flower spikes appearing in late spring. Its compact form can carry color and texture into winter. ## Maintenance This grass is propagated by division. Remove tired flower stems or damaged foliage as needed, and divide crowded clumps when they lose their shape. High Country Gardens lists the selection for mass planting and containers and notes that its seeds attract birds.
