Everillo (Carex oshimensis 'Everillo') is a striking ornamental grass known for its vibrant golden-yellow foliage. Here are some key features and care tips for Everillo Carex:

1. Foliage: The most distinctive feature of Everillo Carex is its arching, linear leaves that are bright golden-yellow. The foliage provides a pop of color in the garden and retains its color throughout the growing season.

3. Sunlight Requirements: Everillo Carex performs best in partial to full shade. While it can tolerate some morning sun, it generally prefers filtered sunlight or dappled shade to maintain the intensity of its golden color.

4. Soil and Moisture: Well-draining soil is essential for Everillo. It can adapt to a range of soil types but prefers consistently moist, but not waterlogged, conditions. Regular watering is important, especially during dry periods.

8. Maintenance: Everillo is a relatively low-maintenance plant. Trim back any brown or damaged foliage in late winter or early spring to encourage fresh growth. Division can be done if the plant becomes overcrowded.

9. Companion Plants: Pair Everillo with other shade-loving plants to create visually appealing combinations. Consider using it alongside other plants with contrasting foliage textures and colors.
