Ornamental Grass: Hakonechloa macra (Hakone Grass, Japanese Forest Grass)
The Hakonechloa macra, more commonly known as Hakone grass, is a beautiful ornamental grass with smooth arching leaves forming attractive, dense mounds. The stunning foliage resembles bamboo but forms a graceful low mound that is easy to maintain. It is also known as Japanese forest grass. As the name implies, it is native to Japan. While it is valued in shade gardens and thrives under a forest canopy’s coolness, the Hakone grass is spectacular as a potted plant. It is slow-growing, cold-hardy and low-maintenance, making it ideal for container gardening, especially if you don’t have time, or the inclination, to repotting every year. Below are tips for growing your Hakone grass and when to cut back at the end of the season.
In the garden, the Hakone grass pairs beautifully with contrasting hostas, and softening the border edging along with lily of the valley ground cover. The Hakone grass does have a flower but is rather insignificant. Knowing where best to plant this moist-loving grass will ensure you have years of enjoyment. The leading H. macra (Hakone grass), with its deep green narrow leaves impart a richness of uniformed colour that offers a gentle texture in any garden. It is the most adaptable and hardy of Hakone grasses and is eye-catching planted next to broad-leaf plants or with flashes of colour from fuchsias or bellflower. Gaining in popularity are the variegated Hakone grasses with gold and yellow that add a spark of brightness and contrast in a shade garden. Planted along with contrasting blue or purple, whether, with a pot or companion plant, it is truly one of the most elegant ornamental grasses to have in the garden. See the list below of recommended Hakone grass cultivars.

Where To Plant And How To Care For Your Hakone Grass
While most ornamental grasses prefer sunny locations, the Hakone grass thrives in part shady to cool filtered part sunny site for best results. Avoid full sunny areas. It grows best in moist, well-drained, organic soil. It is adaptable with soil pH and grows well in either acid, alkaline or neutral soil. Water regularly until it is established, and especially during the hot summer weeks. It is generally slow to establish, but it can tolerate more heat and sun once it does. It is hardy and is long-lived.
The Hakone grass spreads by rhizomes but keeps a more compact form and is considered non-invasive. No pruning or staking is needed. It is slow-growing and requires minimum to no dividing for several years.
The Hakone grass is generally disease and pest-free, and deer resistant.
Hakone Grass Winter And Spring Maintenance
At the end of the season, the leaves will die back, and the plant will go dormant over the winter. There is really nothing to do to it over the winter. In early spring, remove the leaves and cut back the dead stems to ground level. This will provide a tidy area as your Hakone grass emerges again in the spring.
Add a light mix of compost and mulch before new growth starts will set it well for the year. It is a welcome sight in a shady spring garden.
