Hakonechloa macra

Sizes available: 2 quart

Basics: zones 5-9, 12-18" x 24", part sun to part shade, cascading light, grassy green foliage, (current image is probably 'All Gold', this will be grassier green) which turns orange and then tan as the weather cools, can tolerate quite a bit of shade, flowers in mid to late summer, but the subtle sprays of flowers are usually hidden by the foliage, likes moist woodland soils and definitely needs consistent moisture in higher light conditions. Does not like dry, poorly drained, or heavy clay soils. 

Common names: Hakone Grass, Japanese Forest Grass

Family: Poaceae

Origin/Distribution: central Japan

Habitat: damp woods and mountainous regions

More: Lovely texture for the shady parts of the  garden, especially on slopes or by steps that show its waterfall-like growth habit off to best effect. Slow to get going in the spring and slow to mature. I am pretty sure the plant pictured is a cultivar, but it gives you a good sense of the form. H. macra is the straight species and will be greener.

Nursery: Van Berkum
