If you like the color of gold, September (and October) have got to be your favorite months in Japan. Everywhere you turn trees ablaze in golden fruit and sometimes leaves, grab your attention.
It starts with the grasses, the thistles turn golden, and of course, the Japanese plume grasses. Sengokuhara Plain in Hakone is where crowds flock to see the fields of gold.

NATURE IN JAPAN 
Miscanthus is a favorite of mine for Portland landscaping. Even in my own landscape.
Just finished dividing those ornamental grasses in our own yard a few weeks ago. Which provide more new plants, or gifts for other home gardeners.
Its a durable, graceful and attractive plant.
