Ophiopogon planiscapus 'Nigrescens'Black Mondo Grass

The Ophiopogon planiscapus 'Nigrescens', or Black Mondo Grass, is a striking evergreen perennial known for its unique, jet-black, grass-like foliage. Growing to just 20 to 30 cm tall, it forms dense clumps that create a dramatic contrast in garden beds, borders, and containers. In summer, small, bell-shaped, pale pink to lilac flowers emerge, followed by glossy black berries in autumn.

Hardy and low-maintenance, Black Mondo Grass thrives in a variety of conditions, making it a versatile choice for modern, woodland, or Japanese-inspired landscapes.
