How to Iwagumi Plant List (Intermediate Guide)
Stepping up your aquascaping game? Iwagumi aquascapes are elegant, minimalist, and all about balance. But choosing the right plant list is critical for success. In this intermediate guide, we’ll help you select, care for, and arrange the best plants for an Iwagumi aquarium. Whether you’re refining your skills or starting your first Iwagumi layout, this article is for you!
What Is the Iwagumi Style?
The Iwagumi style is a Japanese aquascaping technique that focuses on simplicity and natural beauty. Traditionally, this layout uses a small number of stones (named Suiseki) and minimal plant species to create a peaceful, harmonious underwater scene. Achieving the iconic ‘floating landscape’ look depends heavily on your plant selection and placement.
Key Principles for an Iwagumi Plant List
- Minimalism: Limit your plant selection to two or three species. Simplicity enhances visual impact.
- Low Growth: Most Iwagumi layouts favor carpeting and short foreground plants to accentuate the stonework.
- Subtle Accents: Consider adding one accent plant for contrast or seasonal color variation.
Best Plants for Iwagumi Aquascapes: Intermediate Plant List
Intermediate aquascapers can handle more diverse plant needs, including CO2 supplementation and careful trimming. Here are our top picks:
1. Hemianthus callitrichoides ‘Cuba’ (Dwarf Baby Tears)
Beloved for its dense, vibrant green carpets. It thrives with high light and CO2. Perfect for intricate ground cover around stones—just be prepared for regular trimming.
2. Eleocharis acicularis (Dwarf Hairgrass)
This grass-like plant forms soft, flowing carpets. It’s slightly taller than Dwarf Baby Tears and looks beautiful waving in the current. Great for creating transition zones between stones and backgrounds.
3. Glossostigma elatinoides
With its small, leafed runners, this plant provides a lush, low-growing carpet. Learn more about carpeting plants to improve your Iwagumi design.
4. Micranthemum ‘Monte Carlo’
Known for its resilience and ease of propagation compared to Dwarf Baby Tears. Offers a cushiony, bright-green look—great for those seeking a slightly easier carpet plant.
5. Utricularia graminifolia
For a unique texture, Utricularia graminifolia adds a wild, soft carpet effect. It’s a bit more demanding but makes an eye-catching foreground.
6. Riccardia chamedryfolia (Coral Moss)
Although mosses aren’t always traditional in Iwagumi, this moss can provide contrast on stone surfaces or delicate accents between rocks.
Accent Plants for Intermediate Iwagumi Layouts
While most of the layout is carpet or low-growing, some aquascapers include subtle accents. These can draw the eye or give seasonal interest:
- Hydrocotyle tripartita ‘Japan’ – Adds a playful, clover-like appearance and delicate structure.
- Rotala rotundifolia (for background or accents) – Offers a gentle hint of red and verticality without overpowering the scene.
How to Select Plants for Your Iwagumi Layout
When building your Iwagumi plant list, keep the following in mind:
- Tank Size: Smaller tanks benefit from finer carpet plants, while larger tanks allow for bolder transitions.
- Lighting & CO2: Many intermediate Iwagumi plants require powerful lighting and stable CO2.
- Maintenance: Choose plants that suit your willingness to trim and fertilize regularly.
Planting and Care Tips for Iwagumi Setups
1. Prepare Your Substrate
Use a nutrient-rich substrate for robust root growth. Fine grain soils also help with rooting delicate carpet plants.
2. Plant Densely
Start with lots of plantlets to ensure quick carpet formation and to outcompete algae. Tweezers are great for precise planting.
3. Monitor Growth and Trim
Frequent trimming encourages horizontal spreading. Trim often to maintain that classic open Iwagumi look.
4. Fertilization and CO2
Intermediate plants thrive with regular fertilization and stable CO2. Consider a liquid fertilizer and pressurized CO2 system for best results.
Common Mistakes in Iwagumi Plant Selection
- Choosing too many species – Simplicity is key for balance and harmony.
- Neglecting plant demands – Don’t underestimate lighting and CO2 needs.
- Overcrowding accent plants – Keep accents subtle to avoid distracting from the main layout.
