Carex rariflora, commonly known as looseflower alpine sedge, is a perennial herbaceous plant native to cold, wet habitats including open bogs, wet meadows, and low-elevation heath tundra across Alaska, Maine, and parts of Canada. It typically grows up to 3 feet tall, forming dense tufts of long, narrow leaves that are dark green in color. The inflorescences are relatively inconspicuous, with small, greenish-brown flowers that bloom and set fruit in the summer months. The plant’s structure, with its long leaves and clustered growth habit, contributes to its role in stabilizing soil and establishing wetland areas.

Looseflower alpine sedge is valued for its ability to thrive in wet conditions and is often used in restoration projects for wetland habitats. It is also suitable for water gardens and naturalized areas where its maintenance needs are minimal. This sedge prefers consistently moist to wet soils and can tolerate a range of light conditions from full sun to part shade. While it is not known for showy flowers, its foliage provides texture and greenery throughout the growing season. There are no significant disease or pest issues, but it may require management to prevent it from spreading too aggressively in garden settings.CC BY-SA 4.0
