Melica altissima, commonly known as Siberian melic grass, is a perennial herbaceous plant native to temperate regions of Europe and Asia, including Siberia. It is a clump-forming grass that typically grows to a height of 2-3 feet (0.6-0.9 meters) and is known for its arching, narrow leaves and delicate, nodding flower spikes. The flowers, which appear in late spring to early summer, are not particularly showy but have an understated elegance, with a purplish hue that can add a subtle color to the garden. Siberian melic grass is appreciated for its fine-textured foliage and its ability to sway gracefully in the breeze.

In cultivation, Siberian melic grass is valued for its ease of maintenance and its ability to grow in a wide range of soil types, from clay to sandy soils, as long as they are well-drained. It prefers full sun to partial shade and requires moderate watering, making it a versatile choice for gardeners. It is often used in naturalistic plantings, as an accent in borders, or for mass planting in open spaces. While it is not typically afflicted by serious pests or diseases, it can occasionally suffer from rust or fungal leaf spots. Siberian melic grass is not known to be invasive and generally does not have aggressive roots, making it a safe choice for a variety of garden settings.CC BY-SA 4.0
