Spodiopogon sibiricus, commonly known as Frost Grass, is a deciduous perennial grass native to open woodlands and grasslands of East Asia, including China, Japan, Korea, and parts of Siberia. It typically grows to a height of 3-5 feet (0.9-1.5 meters) and a width of 2-3 feet (0.6-0.9 meters). Frost Grass is notable for its upright, clumping form and fine-textured foliage that turns a striking coppery-gold in the fall, adding seasonal interest to the garden. The inflorescences appear in late summer, producing airy, silvery plumes that persist into winter and provide a unique textural contrast.

Frost Grass is valued for its adaptability and visual appeal throughout the seasons. It is used in cultivation for mass plantings, as an accent in borders, and for its ability to provide winter interest. This grass thrives in full sun to part shade and prefers consistently moist, well-drained soils. It is relatively low maintenance, but it benefits from being cut back in late winter to early spring to make way for new growth. While generally disease-free, it can suffer from rust in humid conditions. Frost Grass is non-invasive and is not known to have aggressive roots, making it a safe choice for gardeners looking to avoid potential problems with plant spread or infrastructure damage.CC BY-SA 4.0
