Stipa lagascae, commonly known as Lagasca’s Needle Grass, is a perennial grass native to the Mediterranean Basin, specifically thriving in dry grasslands, open woodlands, and rocky hillsides. It exhibits a moderate growth rate, reaching heights of 1-2 feet (0.3-0.6 meters) and spreading 1-1.5 feet (0.3-0.5 meters). The plant forms dense tufts of fine, arching leaves, and in spring, it bears inconspicuous green flowers that are followed by more ornamental, feathery seed heads which persist into summer.

Lagasca’s Needle Grass is valued for its low water requirements and its ability to thrive in poor soils, making it an excellent choice for xeriscaping and naturalistic plantings. It is often used in rock gardens, as a ground cover, or for erosion control on slopes due to its dense root system. This grass prefers full sun exposure and is tolerant of drought once established, requiring minimal maintenance. It is adaptable to a variety of well-drained soils, including sandy or loamy types. While generally disease-free, it can occasionally suffer from rust in humid conditions.CC BY-SA 4.0
