Japanese Forest Grass
Hakonechloa macra · Poaceae
Japanese forest grass is the most elegant shade grass we know: its bamboo-like leaves all spill in one direction, forming soft cascades that look combed. It grows slowly, never runs and turns any container into a small piece of Japanese garden. We source our plants in robust nursery quality directly via the Veiling Rhein-Maas.

- Hakonechloa macra
The best-known cultivar is „Aureola“ with gold-striped foliage that positively lights up dark corners. „All Gold“ is entirely lime yellow and slightly more upright, while the green wild form is the most robust and shows the loveliest copper-orange autumn colour.
Unlike most ornamental grasses, Hakonechloa is no sun worshipper: it is happiest in light to partial shade on fresh, humus-rich soil. Full midday sun scorches the yellow cultivars in particular, while deep dry shade beneath shallow-rooted trees leaves it sulking.
The grass emerges late, often not until the end of April — the most common beginner mistake is throwing out the seemingly dead clump in spring. Patience pays off: from May the cascade rebuilds quickly and lasts until frost, taking on warm copper tones in autumn.
As a design element the forest grass is a soloist. In a container a single spilling clump looks like a green wave; in the border it accompanies hostas, ferns, hellebores and hydrangeas. In Japanese-inspired gardens it is classically planted along path edges and over stones, where the leaf cascade can flow.
Care is as simple as it gets: the slow-growing clump stays compact and needs neither division nor shaping. Only in early spring is the old foliage cut close to the ground before the new growth appears — and that is essentially it.

Japanese forest grass is non-toxic to cats, dogs and children and one of the safest container plants for pet households. Nibbled blades do no harm.
Overview: toxic & non-toxic plants for cats, dogs and children
Care
- 01Choose light to partial shade; avoid harsh midday sun.
- 02Provide fresh, humus-rich soil and use quality substrate in containers.
- 03Keep evenly moist — forest grass tolerates neither a dried-out root ball nor waterlogging.
- 04Feed with compost or a little organic fertiliser in spring.
- 05Cut old foliage close to the ground in early spring only; it protects the clump in winter.
- 06Be patient with the new growth: the grass often does not appear until late April.
Frequently asked
- Does Japanese forest grass grow in shade?
- Yes, it is one of the best grasses for shady spots. Light shade or partial shade with fresh soil is ideal. Only in very dark, dry root shade under old trees does it lose vigour, and the yellow cultivars glow a little less in deep shade.
- Is Japanese forest grass winter-hardy?
- Yes, in the border Hakonechloa is reliably hardy to around minus twenty degrees. The foliage dies back in winter and reshoots in spring. Stand container plants in a sheltered spot and never let the root ball dry out completely or freeze solid.
- Why is my forest grass not shooting in spring?
- Usually it is simply too early: Hakonechloa is one of the latest grasses and often only shows itself in late April or early May. Please do not discard the clump before then. If nothing appears by May, winter wet in the pot or a completely dried-out root ball is usually to blame.
- Is Japanese forest grass toxic to cats?
- No, it is non-toxic to cats, dogs and people. That makes it a good choice for balconies and terraces where pets roam — even if cats occasionally repurpose the soft blades as nibbling grass.
