Are you sure you're not referring to 'Gardeners Garters' - Phalaris arundinacea 'Variegata'? This can be a pernicious and highly invasive weed if not kept in check. 'Zebra grass' - Miscanthus sinensis 'Zebrinus' is by contrast, well-mannered and a delight in almost any garden situation. The former has white stripes along the leaves, whereas the latter has soft yellow stripes across the leaves.

The Miscanthus will tolerate a wide range of conditions and can be kept in a large container if wished. Ideally it should be planted in a sunny or very lightly shaded spot in moist, fertile soil. It gradually forms a dense clump up to 1 metre across and nearly 2m. high when established. It can be divided in spring if it becomes too large. It is never invasive and makes a bold statement if planted in a prominent position.
