Carex oshimensis ‘Evercolor® Everest’ Carfir01 PP20,955 prefers a shaded plant to avoid direct sunlight, which can scorch its leaves. Ensure the soil is consistently moist but not waterlogged by watering regularly. Incorporate organic mulch around the base to help retain soil moisture and suppress weeds. Prune away any dead or damaged leaves in late winter or early spring to promote healthy new growth. This versatile plant works well in borders, containers, or as an accent in mixed plantings.
