Summary

Trisetum spicatum, commonly known as Spike Trisetum, is a deciduous perennial grass native to a variety of habitats including alpine meadows, tundra, and open subalpine forests across North America, Eurasia, and South America. It typically forms dense clumps of erect stems that can range from a few centimeters to over one meter in height, adapting well to the harsh conditions of high altitudes. The narrow leaves of Spike Trisetum are mostly basal, contributing to its tufted appearance. Its inflorescence is a narrow, shiny spike that can be green, purple, or brownish, and varies in length from a few centimeters to an impressive 30 to 50 centimeters at its maximum.

Spike Trisetum is valued for its hardiness and ability to thrive in cool, mountainous environments. It is often used in rock gardens, alpine collections, and naturalized areas where its modest water requirements and tolerance for slow-draining soils are advantageous. While it prefers part shade or full sun, it is adaptable to a range of light conditions. This grass is not commonly afflicted by diseases or pests, making it a low-maintenance option for gardeners. However, its preference for cooler climates should be considered when planting in warmer regions.CC BY-SA 4.0
