Iris graminea, commonly known as Grass-leaved Flag, is a rhizomatous perennial herb native to meadows, grassy slopes, and open woodlands in southern Europe and parts of Russia. It typically grows to a height of 12-18 inches (30-45 centimeters) and has a clumping form with narrow, grass-like leaves. The flowers, which appear in late spring to early summer, are notable for their purple or violet-blue color and distinctive plum-like fragrance. They are relatively showy and add a splash of color to garden settings.

Grass-leaved Flag is valued for its ornamental flowers and ease of maintenance. It is often used in perennial borders, rock gardens, and as a ground cover. This Iris species prefers full sun to partial shade and requires well-drained soil. It is drought-tolerant once established and can handle a variety of soil types, though it thrives in moderately fertile conditions. While generally disease-resistant, Iris graminea can be susceptible to iris borer and root rot if grown in overly wet conditions. It is hardy to USDA Zones 3-9, making it a versatile choice for gardeners in a wide range of climates.CC BY-SA 4.0
