COMMONLY known as lilyturf, this striking black grass-like perennial which originates from Japan looks brilliant framing the front of a border with its curved, strap-shaped purplish-black leaves, which grow to around 35cm (14in) long.

It can also look effective in clumps in rockeries, alongside yellow or acid foliage. The purplish white summer flowers are followed by fleshy blue-black berries. Grow it in full sun to maintain its colour.

It contrasts well with vivid green shrubs or acts as an effective ground cover combination set against gold variegated Hakonechloa macra.

In contemporary gardens, put two or three plants in a metal or granite pot for a more modern effect. Older leaves may go brown in winter, but these can be removed individually. Plants can be divided in late winter and early spring.
