Cryptocoryne Yujii UNS Tissue Culture
Plant Profile
This crypt was named in honor of its discoverer, Mr. Yuji Sasaki, who first found the species in Sarawak, Borneo, in 2002. It forms compact rosettes of deep reddish-brown to olive-green leaves with subtly ruffled margins, bringing rich, earthy tones directly to your foreground or midground zones. As with all crypt plants, it can be sensitive to sudden parameter shifts and strongly objects to being relocated once planted.
Tissue Culture cups ensure your aquascape gets a super clean starting point. Lab‑grown and fully sterile, it arrives without pests, snails, duckweed, or any unwanted algae. It’s the go‑to option for anyone who wants peace of mind when adding fresh greenery to a carefully maintained setup.
Key Features & Benefits
- Compact reddish-brown to olive foliage with ruffled edges creates distinct texture.
- Can be grown emersed in high-humidity setups, where mature plants may produce flowering spathes.
Care & Planting Instructions
- Thoroughly wash away the nutrient gel from the roots with your fingers before parting it out into manageable portions.
- Use fine-tip pinsettes to push roots deep into quality aquarium soil, as Crypt species are heavy root feeders.
- Insert root tab fertilizers if using an inert substrate like sand or gravel to supply essential subterranean nutrients.
- Inject pressurized CO2 for faster growth and fuller foliage density, though not required for long-term health.
- Choose a permanent spot from day one; moving an established plant will likely trigger leaf loss.
- Crypt species can be grown emersed in high-humidity setups or submerged in aquariums. Propagate by splitting the rhizome or replanting new growth shoots.
- Don't discard the plant if leaves dissolve early on; see our guide to managing Cryptocoryne melt to help your plant recover smoothly.

Frequently Asked Questions
1. What makes Cryptocoryne Yujii unique compared to other crypts?
Discovered in Borneo by Yuji Sasaki, this rare species stays relatively compact while developing deep reddish-brown and olive tones with subtle leaf ruffles, making it an exceptional foreground feature.
2. How do I help my Cryptocoryne recover if it melts?
Trim away dissolving leaves, maintain stable water parameters, and leave the root system undisturbed so it can rebuild new foliage. Check our guide to managing Cryptocoryne melt for full recovery steps.
3. Can Cryptocoryne Yujii be grown without CO2 injection?
Yes, like most Cryptocoryne species, Yujii is adaptable and will grow reliably in low-tech setups with low-to-moderate light, though CO2 injection speeds up root establishment and growth rate.
