What Is Japanese Grass?

When people refer to Japanese grass, they’re usually talking about selections of Hakonechloa macra, also known as Japanese Forest Grass. This stunning perennial is native to the shady woodlands of Japan. Its soft, green blades form mounds that swish with the lightest touch, providing a calming, almost zen-like quality perfect for woodland gardens, city retreats, and contemporary landscapes. Japanese grass adapts well to New Zealand climates, thriving in part-shade with moisture-retentive, well-drained soils.

Popular Varieties of Japanese Grass

There’s a delightful range of Japanese grass varieties to choose from for your planting schemes:

• Hakonechloa macra (Japanese Forest Grass) is the classic original form, renowned for its seas of lush, lime-green foliage.
• Hakonechloa macra 'Aureola' (Japanese Golden Grass) stuns with bold golden-yellow stripes on its leaves, brightening up shaded spaces.
• Hakonechloa macra 'Albostriata' introduces elegant creamy-white striping for subtle interest among other foliage plants.
• Hakonechloa 'Albovariegata' provides even more contrast with its white-edged, variegated leaves for a sophisticated look.

Another group sometimes referred to as Japanese grass is Miscanthus. While larger and more upright, Miscanthus sinensis creates beautiful tall plumes and is perfect for structure or screening in larger gardens.

Design Uses and Planting Tips

Japanese grass is celebrated for its versatility. Traditional Japanese gardens use it to soften paths, spill over rockwork, or sweep around water features. In New Zealand, it’s ideal for shady borders, underplanting trees, creating ground covers under shrubs, or cascading from pots. Plant Japanese grass en masse for a glowing haze of colour, or tuck a few clumps into corners where other perennials struggle. Its gentle nature makes it an excellent companion for hostas, ferns, and maples.

Caring for Japanese Grass

Japanese grass is low-maintenance but rewards attentive care. Plant in partial or dappled shade, giving it protection from harsh summer sun. Ensure the soil stays evenly moist, especially in dry periods, but avoid waterlogged conditions. Japanese grass rarely falls victim to pests or diseases, and in New Zealand’s mild regions, it may remain semi-evergreen. In late winter, cut back tired foliage to make way for fresh growth.

Whether you choose the classic green of Hakonechloa macra (Japanese Forest Grass), the variegated beauty of Hakonechloa macra 'Aureola' (Japanese Golden Grass), or explore statement forms like Miscanthus sinensis, Japanese grass brings grace and long-lasting appeal to any garden.
