Ophiopogon planiscapus 'Nigrescens' (Black Mondo Grass)

🌿 Ophiopogon planiscapus 'Nigrescens' (Black Mondo Grass)

Ophiopogon 'Nigrescens', or Black Mondo Grass, is a bold, architectural ground cover with narrow, jet-black foliage that creates a dramatic contrast in borders, containers, or gravel planting. Though grass-like in habit, it is technically a perennial in the lily family — evergreen, low-growing, and slowly spreading via underground rhizomes. Pale lilac flowers appear in midsummer, followed by small black berries that add seasonal intrigue.
Specifications:

• Height: 15–20cm

• Spread: 30–40cm

• Flowering: July to August 🌸

• Position: Full sun to partial shade

• Soil: Moist but well-drained; tolerant of clay, loam, or sandy soils

🌿 Note for Isle of Wight planting:
Black Mondo Grass performs well in the island’s mild climate and handles coastal conditions with ease when planted in sheltered spots. It offers excellent contrast against gravel, stone, or pale foliage. In heavier clay areas, improve drainage before planting. This is a low-maintenance choice that delivers high visual impact all year round.
