Elymus magellanicus, commonly known as Magellan Wheatgrass, is a semi-deciduous perennial grass native to the temperate grasslands and open areas of Southern South America, including Patagonia and the Falkland Islands. It typically grows to a height and width of 0.8-1 feet (0.2-0.3 meters), forming dense tufts of striking blue-green foliage that provide a unique texture in the garden. The plant’s inflorescences are subtle, with small, wheat-like flowers that may go unnoticed, but its foliage is the main attraction.

Magellan Wheatgrass is valued for its low stature and attractive, blue-green leaves, which add color contrast in garden designs. It is often used in rock gardens, as a ground cover, or in borders where its color can complement other plants. It thrives in full sun and requires well-drained soil, making it suitable for xeriscaping. While it prefers medium amounts of water, it can tolerate some drought once established. Gardeners should be aware that in some conditions, it may self-seed and spread, requiring some maintenance to keep it in check.CC BY-SA 4.0
