Japanese Forest Grass
Hakonechloa macra
A graceful, cascading grass whose arching, bamboo-like leaves bring soft texture to shade, edging a path or massed as a groundcover, and deer avoid it. It spreads slowly without being invasive. It needs rich, steadily moist, well-drained soil out of hot sun, and it's happiest where summers are cool.

Japanese Forest Grass at its mature size
A mature Japanese Forest Grass grows 12 to 18 inches tall and 12 to 24 inches wide.
Drawn to scale beside a 5 ft 9 in person. With VeraScape, you see it at this size in your own yard.

Through the year
What Japanese Forest Grass looks like month by month in a typical zone 6–7 garden.
Dormant · Dec–Feb
Dried pale straw-tan leaves, still arching but partly collapsed, no green left.
Below ground · Mar–Apr
Cut back; new shoots barely out of the ground.
In leaf · May–Oct
Cascading mound of arching plain bright green leaves.
Fall · Nov
Early fall: the mound still mostly the same fresh green it has now, with a coppery orange and pink-red blush only on the blade tips and outer blades, about a third of the colour; reads green with copper highlights from a distance, not solid orange, not dry or brown.

Spacing
VeraScape spaces plants so their grown canopies just touch. For Japanese Forest Grass, that’s about 1.5 ft apart, center to center.
Place a row in your own yard and VeraScape spaces them at their mature width, so you can see whether they’ll crowd the walk.
