Melica altissima, commonly known as Siberian Melicgrass, is an ornamental perennial grass valued for its elegant foliage and attractive inflorescences. This species belongs to the genus Melica, a group of grasses found across temperate regions of the Northern Hemisphere. Siberian Melicgrass is recognized for its graceful upright growth and its ability to add texture and movement to garden settings. Physically, Melica altissima typically forms dense clumps of erect, unbranched culms that reach heights of 60 to 120 centimeters (approximately 2 to 4 feet). The leaves are linear, flat, and typically 20 to 40 centimeters long, with a smooth texture and a green to bluish-green coloration. The ligule, a membrane at the junction of the leaf blade and sheath, is notably long and membranous, often appearing split. The most striking feature of Melica altissima is its inflorescence, a panicle that is typically 15 to 30 centimeters long. This panicle is often loose and open, bearing spikelets that are usually purplish or greenish-brown. The spikelets are ovate and contain two to four florets, each subtended by glumes. The flowering period generally occurs in late spring to early summer, followed by the development of small caryopses, which are the true fruits of the grass. The native range of Melica altissima extends across parts of Eastern Europe and Western Asia, including regions of Siberia, from which it derives its common name. It thrives in a variety of natural habitats, often found in open woodlands, meadows, and along the edges of forests. In cultivation, Siberian Melicgrass prefers well-drained soils and full sun to partial shade. It is known to be relatively drought-tolerant once established and is hardy in USDA zones 4 through 8, demonstrating good resilience to cold temperatures. Its adaptability makes it a suitable choice for various garden designs, including perennial borders, rock gardens, and naturalistic plantings. While primarily grown for its ornamental qualities, Melica altissima contributes to its ecosystem by providing habitat and food for small wildlife. Its seeds are consumed by birds, and its foliage offers cover. There is no widespread documented use in agriculture, medicine, or culinary practices for this species. An interesting characteristic of Melica altissima is its ability to naturalize in suitable conditions, though it is not typically considered invasive. The grass reproduces both by seed and by rhizomes, which contribute to its clumping habit. The delicate structure of its inflorescence makes it particularly attractive when swaying in the breeze, and it is also frequently used in dried floral arrangements due to its enduring form and color. The plant's overall aesthetic appeal lies in its refined appearance, offering a subtle yet significant presence in the landscape.
