Ophiopogon planiscapus 'Nigrescens' (Black Mondo Grass) - A slow growing evergreen perennial with black grass-like leaves. It can grow to 8 inches tall by 1 foot wide with individual leaves 10 inches long and less than 1/4 inch wide with new growth very dark green towards the base of the leaves and darkening towards the tips to become one the blackest plants that we know of. Clusters of spikes on which whitish lilac flowers appear in summer and are often followed by dark, nearly black berries in fall. Best in part sun or light shade, with regular watering. Hardy at least to USDA Zone 6a (-10F) Great for a groundcover or in containers - very slow growing. According to the International Liriope and Ophiopogon Cultivar Register this plant should not be called by by the Latinized cultivars names 'Nigrescens' or 'Arabicus' since the naming conventions set down in The International Code of Nomenclature for Cultivated Plants (ICNCP) prohibited this use for any cultivar name use after 1958. The name the is International Liriope and Ophiopogon Cultivar Register recommends be used is Ophiopogon planiscapus 'Kokuryu' it was introduced into cultivation in the US from Japan under the name Liriope 'Kokuryu' by R.E Perdue of the USDA in 1959 who obtained it from Nakada Nursery in Angyo, Japan but there is a certain amount of disagreement about the correct name for the plant. Some consider the species Ophiopogon planiscapus to naturally have black foliage and simply list this plant as a species. It is also sometimes listed as 'Black Dragon', 'Ebony Knight' or 'Arabicus'. The oldest name we have found in usage in is Ophiopogon arabicus as a plant accessioned by the Huntington Botanic Garden in 1956 that came from Jimmy Giridlian's Oakhurst Garden but this illegitimate use of "arabicus" as a specific name likely disqualifies it as a cultivar name. The cultivar name 'Nigrescens' however was used for another plant the Huntington received from Oakhurst Garden in 1957, accessioned as HBG#25997, which would have been before the ICNCP 1958 ruling prohibiting the use of Latinized names. In the 1976 Hortus III: A Concise Dictionary of Plants Cultivated in the United States and Canada, compiled by the Liberty Hyde Baily Hortorium at Cornell University, this plant is listed as Ophiopogon planiscapus 'Arabicus' but in the 1994 Index of Garden Plants by The Royal Horticultural Society it is listed as Ophiopogon planiscapus 'Nigrescens'. We also have a thin smaller leaf form that we call Ophiopogon planiscapus 'Teague's Black'

This information about Ophiopogon planiscapus 'Nigrescens' displayed on this web page is based on research we have conducted in our horticultural library and from reliable online resources. We also will relate observations we have made about it as it grows in our nursery gardens and other gardens visited, as well how our crops have performed in containers in the nursery field. Where appropriate, we will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant.
