Koeleria crassipes, commonly known as Prairie Junegrass, is a perennial grass native to a variety of habitats including dry grasslands, open woodlands, and rocky slopes in Europe, particularly in Spain and Portugal. It typically grows to a height of 0.6-2 feet (0.2-0.6 meters) and a width of 0.8-2 feet (0.2-0.6 meters). This grass forms dense tufts of fine, blue-green foliage that is particularly attractive during the growing season. The inflorescences are narrow, spikelike panicles that appear in early summer, with a muted green or silver color that can add a subtle elegance to garden settings.

Prairie Junegrass is valued for its low maintenance requirements and its ability to thrive in poor soils with good drainage. It is often used in naturalistic plantings, as an accent in rock gardens, or for erosion control on slopes. It is drought-tolerant once established, making it suitable for xeriscaping. While it prefers full sun, it can tolerate light shade. It is not commonly afflicted by serious pests or diseases, but overwatering or poor drainage can lead to root rot.CC BY-SA 4.0
