Suggested uses: specimen, containers, sunny border, summer screen, Japanese garden, dried arrangements

When divide: when it shows signs of life in the spring, continuing until the new growth is about 18" tall; only in the spring (further info on dividing grasses)

When to plant or transplant: plant bare root plants only in late spring to early summer, when the soil is warm, about the same time you plant your bean or corn seeds. The roots will grow only in warm soil. Planting too early in the spring may cause the roots to rot. Similar story in the fall when the roots may not grow enough to establish before the cold and wet of winter, resulting in the demise of the plant.

When to cut back: we enjoy the foliage of Miscanthus so much that we like to leave it standing until the new growth starts to appear, possibly as late as May. We also like the combination of the tan foliage and spring bulbs. Cut back to about 6" from the crown of the plant.

Partner with: other sun-loving perennials, Eupatorium cannabinum, Persicaria polymorpha

Season of interest: July till spring; will likely remain standing all winter

Drought tolerance rating: 3 (water to root depth once a week); further info

Recommended spacing between plants: 75-125 cm (30-50") why such a difference?

Native to: Miscanthus sinensis is native to marshes, slopes, mountainsides of Eastern Asia and west to Africa. It is a source for thatching material for temple roofs and homes.

Pronunciation: Miscanthus (mis-KAN-thus) sinensis (sin-EN-sis)
