Feather Falls Sedge
Carex oshimensis 'Feather Falls' is a unique ornamental grass known for its cascading, bright green foliage, resembling a gentle waterfall, which adds a graceful texture to garden landscapes. It forms a low-growing, rounded mound, creating an elegant, flowing appearance. This non-flowering grass thrives in full sun to partial shade and requires moderate watering with well-drained soil. 'Feather Falls' is low-maintenance, needing only occasional trimming to remove dead or damaged foliage. While not a significant wildlife attractor, its cascading form can provide shelter for small insects and animals.

Design tip
Use it as a steady framework plant, repeating it along a bed to tie separate plantings together. It takes sun or light shade, which makes it useful along the changing light of a bed edge or a partly shaded border.
