Asplenium ‘Osaka’ is a compact bird’s nest fern with tightly crinkled, glossy green fronds that form a neat, upright rosette. Its sculptural shape adds texture to shaded garden beds, underplanting, or pots in protected outdoor areas. Prefers part to full shade with moist, well-drained soil—ideal for humid, sheltered positions. Low-maintenance and well-suited to subtropical gardens.
