Dwarf Sagittaria (Sagittaria subulata) is a popular aquatic plant commonly used in freshwater aquariums, especially in planted tanks and aquascapes. Here’s an overview of this plant:
Scientific Classification
Scientific Name: Sagittaria subulata
Common Names: Dwarf Sagittaria, Narrow-leaf Sagittaria
Family: Alismataceae
Origin: Eastern North and South America (native to coastal regions)
Characteristics
Size: Typically 5–15 cm (2–6 inches) tall; can grow taller in high-light or CO₂-rich environments.
Leaves: Narrow, ribbon-like, bright green; grass-like appearance.
Growth Form: Forms dense, carpet-like patches via runners.
Care Requirements
| Feature | Details |
|---|---|
| Light | Moderate to high; low light slows growth and reduces carpeting behavior |
| CO₂ | Not required, but CO₂ supplementation accelerates growth |
| Substrate | Nutrient-rich preferred (e.g., aqua soil or root tabs) |
| Water Temp | 20–28°C (68–82°F) |
| pH Range | 6.5–7.5 |
| Hardness | Soft to moderately hard water |
Propagation
Method: Sends out runners which grow into new plants; can be trimmed and replanted
Growth Rate: Fast under optimal conditions
Pros
Easy to grow, beginner-friendly
Great for foreground or midground placement
Provides shelter for fry and shrimp
Helps reduce algae by nutrient uptake
Considerations
Can grow tall in high-light/CO₂ setups (less “dwarf” in appearance)
May need regular trimming to maintain a tidy carpet
