The Story
Plant Bio
Ophiopogon japonicus, commonly known as mondo grass, is a low-growing, evergreen perennial forming dense tufts of dark green, grass-like foliage. Small, bell-shaped, pale lilac to white flowers appear in summer, followed by glossy, blue-black berries.
This species is an excellent, tough, and drought-tolerant groundcover for shady areas, valued for its fine texture and evergreen nature. It spreads by rhizomes to form a dense mat.
