Ophiopogon General Information

Black Mondo Grass resembles Liriope and is a member of the Lily family. Plant in full sun to retain deep black color on strap-like foliage. Low maintenance choice for slopes, mass planting and rock gardens. Royal Horticultural Society and Missouri Botanical Garden Award Winner. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Ophiopogon Plant Care

Requires full sun for deepest black foliage. Prefers a moist, well-drained soil. Mow foliage at highest cutting height in late winter before new growth. Slow growing, clumping perennial.

Plantable Pots

Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!

100% Guarantee

We offer a 100% unconditional guarantee for all our perennials to reach you in good condition and to grow. If you're not satisfied, we'll reship or refund immediately. Please don't hesitate to contact us if you have questions or concerns—we share your passion for gardening and want your new plants to thrive in your border!
