About Stout Blue-eyed Grass

Stout Blue-eyed Grass is a charming native perennial that brings a touch of the iris family's elegance to your landscape. Despite its name and grass-like foliage, it is not a true grass but a member of the Iridaceae family. Reaching up to 2 feet in height, this species is more robust than many of its relatives, forming attractive clumps of narrow, sword-shaped leaves. In mid-spring, it produces a profusion of star-shaped, violet-blue flowers, each highlighted by a bright yellow 'eye.' These blooms are a magnet for small native bees and other pollinators. Native across most of the eastern and central United States, it thrives in moist meadows and open woodlands. It is remarkably versatile, performing well in full sun to partial shade and medium-wet to medium-dry soils. Its clump-forming habit and delicate floral display make it a perfect choice for rock gardens, path edges, or as a charming filler in a native meadow. This resilient plant is short-lived but often self-seeds, ensuring a lasting presence in your garden.
