Japanese Forest Grass Hakonechloa macra 'All Gold'
ABOUT
The Hakonechloa macra 'All Gold', commonly known as Japanese Forest Grass or Hakone Grass, is an ornamental grass renowned for its vibrant foliage. This cultivar stands out with its striking golden-yellow leaves that cascade gracefully, much like a golden waterfall or a fountain of bright foliage. The leaves are slender and arching, creating a soft, fine-textured appearance that shimmers in the light and can add a touch of luminosity to shaded areas. Throughout the seasons, the color intensity of Japanese Forest Grass 'All Gold' can vary, displaying the brightest tones in partial sun where it glows warmly. In deeper shade, the gold may present with slightly more muted undertones, yet it maintains its appealing hue. The leaves may also take on hints of chartreuse, adding depth and variation to the display. In the warmer months, delicate flower spikes may emerge, adding to the plant’s visual interest, but they are often considered secondary to the striking foliage. The graceful habit of this grass and the texture-rich leaves make it a popular choice for adding contrast and color in landscape design, container gardens, and as an accent plant in shaded gardens.

WaterJapanese Forest Grass prefers consistently moist soil, so it should be watered regularly, especially during the growing season. The aim is to keep the soil evenly moist, but not waterlogged. It typically requires about 1 inch of water per week, either from rainfall or manual watering. During hot, dry spells, it may need additional water, but always check the soil moisture to avoid overwatering. Over the winter, when the plant is dormant, watering can be reduced considerably.
LightJapanese Forest Grass thrives in partial shade but can tolerate a few hours of morning sunlight. It is best situated in a spot that receives dappled sunlight throughout the day, avoiding the intense afternoon sun which can scorch its delicate leaves. The ideal location would provide bright but indirect light, which promotes the vibrant golden color of its foliage.
TemperatureJapanese Forest Grass is hardy and can tolerate a range of temperatures, but it does best in areas where the temperature stays between 40°F and 85°F. It can survive in temperatures as low as 20°F and as high as 90°F, but outside of its comfort range, the plant may experience stress or damage. The ideal growing conditions include moderate temperatures with high humidity.
PruningPruning Japanese Forest Grass isn’t strictly necessary but can help maintain its shape and encourage new growth. Pruning should be done in late winter or early spring before new growth begins. You can cut back the foliage to about 3 inches above the ground every few years, which refreshes the plant and helps prevent the center from dying out. The best time for pruning is just as the snow melts or as the ground is no longer frozen.
CleaningAs needed
SoilHakone Grass thrives in a soil mix with good drainage, slight acidity to neutral pH (5.5 to 7.0). A mixture of loam, compost, and pine bark or peat moss often works best, ensuring nutrients and moisture retention while preventing waterlogging.
RepottingHakone Grass, or Japanese Forest Grass, should be repotted every 2 to 3 years. It's best to do this in the spring when the plant begins to show new growth, to minimize stress and encourage quick establishment in the fresh soil.
Humidity & MistingJapanese Forest Grass prefers average to high humidity levels but is quite adaptable. Aim for 40-60% relative humidity for optimal growth; however, it can tolerate lower humidity levels without significant adverse effects.

Life cycleHakone grass 'All Gold' begins its life as a seed, although it is more commonly propagated by division. Once germinated or established, it grows into a clump-forming perennial with striking golden-yellow foliage. During spring and summer, it reaches maturity and thrives, producing arching leaves and contributing to its mound-shaping habit. As an ornamental grass, it does not have a pronounced flowering stage, but it can produce inconspicuous flower spikes in late summer. In autumn, its leaves may take on shades of pink or red before the plant enters dormancy in winter. With the return of warmer temperatures in spring, Hakonechloa 'All Gold' breaks dormancy and begins a new growth cycle.
PropogationPropogation time
Spring-Early Summer
The Japanese Forest Grass 'All Gold' is typically propagated by division, which is best done in the spring just as the new growth begins to emerge. This is the most popular method of propagation for this ornamental grass. To propagate by division, carefully dig up the entire clump of the grass and gently separate it into smaller sections, each with roots and shoots. Replant these divisions at the same depth they were growing previously, spaced about 12 to 18 inches apart to give them room to grow. Water the new divisions well to help establish them. It's important to keep the soil consistently moist but not waterlogged during the first growing season to ensure a successful establishment.
