Ophiopogon planiscapus 'Kokuryū', is a small evergreen perennial with almost completely jet black foliage made up of fine, arching straps. It is still commonly referred to by the name 'Nigrescens'.

This "snake's beard" thrives in humus-rich, cool but well-drained soils, preferably neutral to acidic, in gentle sun, partial shade or full shade.

The Botany


This plant belongs to the Asparagaceae family.

The wild species is native to central and southern Japan, where it grows in woodlands, thickets, plains and on lower slopes.

It is a rhizomatous perennial, slightly stoloniferous. Its leaves are mostly evergreen, though they can be damaged by hard frosts.

This cultivar 'Nigrescens' has received the Award of Garden Merit from the Royal Horticultural Society. It is distinguished by its purplish black, almost ebony leaves, shorter than those of the species and highly decorative.

The plant forms a dense clump 20 to 25 cm tall and 30 cm across, with slow growth. The leaves are narrow, leathery and arching, measuring 20 to 30 cm in length.

In July and August, small bell-shaped flowers in lilac-pink to pale mauve appear on short, flattened stems. They measure 6 to 7 mm across. The fruits are round, glossy and blue-black to black, and are decorative in their own right. 

The Myth

It goes by the common names of black mondo grass, snake's beard or turquoise berry plant. 'Nigrescens', 'Nigra' and 'Black Dragon' are all considered horticultural synonyms of 'Kokuryū'.

The name Ophiopogon comes from the Greek and evokes a "snake's beard"; 'Kokuryū' means "black dragon" in Japanese.
