Gardening 101: Hakone Grass

Hakone Grass, Hakonechloa: “Japanese Forest Grass”

Think of it as Cousin Itt style for the garden. Low-growing clumps of Hakonechloa macra grass add floppy, shaggy style to a landscape.

Native to Japan’s Mount Hakone, hakone grass is happiest in rich, moist soil and part shade and is a good choice if you need a well-behaved ground cover, a low border, erosion control on a hillside, or a plant to spill over the side of a container.

Is hakone grass the right plant for your garden? Read on to find out.

‘Aureola’, with variegated foliage and slender, long leaves, reflects light and can brighten a dark spot or focus attention on a quiet corner of the garden.

Delicate leaves spill out of the center of a clump of hakone grass, which typically grows to heights of 16 to 26 inches.

Cheat Sheet

• Not all hakone grass cultivars have chartreuse foliage: ‘Beni-Kaze’ (which means “red wind”) has green foliage that turns a purply red in autumn; ‘Nicolas’ has solid green leaves that turn to a fiery orange in fall, and ‘Albo-Striata’ is a variegated variety with white stripes.
• With long, thin leaves that bring to mind the foliage of bamboo, hakone grass is a good choice for use in a Japanese-style garden.
• Like most grasses, Hakonechloa ripples like waves in a breeze, adding motion and life to a garden.

Keep It Alive

• Hakone grass thrives as a perennial in USDA growing zones 5 to 9.
• Deer-resistant and low-maintenance, hakone grass will require little beyond an evenly moist environment and well-drained soil.
• Divide and transplant clumps in spring.

Hakone grass dies back in late winter. See more at Gardening 101: How to Care for Perennial Grasses.
