This impressive ornamental grass looks amazing when everything else has died down in the winter months, its large, loose, golden oat-like flowers forming a semi transparent screen.

Also known as giant feather grass or Spanish oat grass, it forms neat hummocks of narrow green leaves, while the flowerheads are carried on erect stems to 1.5m (5ft) tall in early summer, turning a deep golden brown as they age.

This amazing grass needs an uncluttered setting and looks even better against a dark background.

The stems make an attractive feature over winter, so wait until early spring to cut them down, along with any dead leaves.

Grow as a specimen or as a screen at the back of a border. They do best in full sun in fertile, well-drained soil.
