Know before you buy
Yes, Festuca idahoensis maintains its blue-green to silver-blue foliage year-round. However, its appearance may vary slightly depending on the severity of winter temperatures within its hardiness zones of 4-8.
Since this grass has a mature spread of 10 inches, you should space them approximately 10 to 12 inches apart on center. This allows each clumping plant enough room to thrive while creating a cohesive, filled-in look.
No, Idaho Fescue is highly drought-tolerant once it has established a healthy root system. It is well-adapted to the Pacific Northwest climate and generally requires minimal supplemental irrigation.
For the best performance and to maintain its compact, clumping habit, this grass requires full sun. Planting it in too much shade may cause the foliage to lose its vibrant color and lead to a less dense growth pattern.
While it is low-maintenance, you can tidy up the plant in late winter or early spring by gently combing through the foliage to remove any dead blades. This helps keep the clump looking fresh and encourages new growth for the coming season.
