Dimensionsin zone #5 where I garden, 12 by 12 inches is a good starting point (not including flower scape), probably larger in warmer zones, forms a dome shaped tuft, look best in groups
MaintenanceCut of seed heads are the seeds will fall to the soil and germinate. Although I have a few plants that have lasted for many years, they seem to die out in the center and need dividing to maintain vigor.
Propagationeasy by division, the clumps can be pulled apart into small separate little plants and rooted if you need a lot, the straight species Festuca glauca can be grown from seed but the cultivars will not come true from seed and must be vegetatively by division
Native SiteOriginally native to France.
Misc FactsOriginally described by French naturalist Dominique Villars. Species name glaucus refers to the pale blue-grey foliage. AKA: Blue Fescue, Blue Mountain Grass, Grey Fescue.
Author's NotesIt takes a bit of work to keep this plant growing. A planting in groups of 3-5 or more can be impressive. I have used lots of these plants in gardens, grew many at my nursery and wouldn't classify them has hardy and easy to grow has Daylily or Hosta.
