Ophiopogon Pusillus
Plant Profile
Ophiopogon pusillus, widely recognized by scapers as Dwarf Mondo Grass, is an evergreen perennial native to East Asia that forms dense, fountain-like tufts of slender, arching dark green foliage. Its fine grass-like blades create an immediate visual contrast against pale driftwood branches, light river stones, or flat sheet mosses along the enclosure floors and moist paludarium banks. Fun fact: despite its convincing ornamental grass disguise, it actually belongs to the asparagus family (Asparagaceae).
Key Features & Notes
- Arching, dark green ribbon foliage forms tidy, fountain-like tufts that add grassy scale.
- Strictly terrestrial grower that will deteriorate and rot if planted underwater in an aquarium.
- Pairs naturally as a clumping floor accent with other humidity-loving plants in humid setups.
Care & Planting Instructions
- Prep the plant by removing it from the pot and clearing all rockwool from the roots.
- Divide the cluster into smaller plugs if desired, and press the fibrous roots into a loose, well-draining tropical soil blend of bark, pumice, and perlite, keeping the crown level with the soil line.
- Provide partial shade or moderate indirect lighting; avoid harsh direct light, which will scorch the narrow blades and bleach their deep green color.
- Maintain steady ambient humidity while keeping the root zone evenly moist, ensuring excess water drains away freely so the rhizome base never sits in stagnant mud.
- Snip aging or yellowed outer blades near the soil line using sharp scissors to keep clumps compact and clean.
- Ophiopogon pusillus are terrestrial plants, and being submerged will result in the death of the plants.

Frequently Asked Questions
1. Can Ophiopogon pusillus grow underwater in an aquarium?
No. Even though fish stores often sell Mondo Grass submerged in display tanks, it is strictly a terrestrial perennial and will slowly drown and rot if kept underwater.
2. How do you propagate Ophiopogon pusillus in a terrarium?
Lift an established clump and divide the root mass and rhizome into smaller rooted sections using clean shears, then replant each division into moist, aerated substrate.
3. Why are the leaf tips turning yellow or brown on my Mondo Grass?
Brown or yellowing tips generally point to waterlogged substrate in a poorly drained drainage layer, exposure to intense direct lighting, or dry air drafts.
