🌿 Overview

Sagittaria subulata, also known as Dwarf Sagittaria, is a low-maintenance, creeping aquatic plant native to North and South America. Its upright, grassy leaves form carpets and dense foreground layers, making it a staple for nature-style aquascapes and community aquariums.

It is beginner-friendly, tolerant of a wide range of water parameters, and can thrive in low-tech tanks. While CO₂ injection accelerates growth and produces denser carpets, this plant adapts well without supplementation.

🍃 Appearance

• Bright green, narrow, grass-like leaves
• Forms dense carpets or low mats
• Height: 5–15 cm
• Ideal for foreground placement or gentle midground coverage in small tanks
• Provides a natural, lush look and excellent hiding places for fish and shrimp

🌿 Plant Type (Hard/Soft)

• Type: Creeping stem / grass-like plant
• Category: Soft aquatic plant
• Growth rate: Moderate

🌡️ Ideal Water Temperature

• 18°C – 28°C (64°F – 82°F)
• Tolerates a wide range of tropical freshwater aquarium temperatures

💡 Lighting Conditions

• Moderate lighting recommended
• High lighting produces denser, more compact carpets
• Low lighting slows growth and may reduce leaf density

🌿 CO₂ Requirement

• Optional
• CO₂ supplementation improves growth rate, carpet density, and leaf color

⚗️ Ideal pH Level

• pH: 6.0 – 7.5
• Slightly acidic to neutral water preferred

💧 Other Requirements

• Substrate: Soft, nutrient-rich substrate promotes rooting and dense carpet formation
• Fertilization: Benefits from root tabs and liquid fertilizers
• Water hardness: Soft to moderately hard
• Regular trimming maintains a compact foreground and encourages lateral spreading

🌱 Propagation

• Propagates via runners
• New shoots emerge from stolons and form dense carpets
• Can quickly cover substrate under optimal conditions

💡 Do You Know?

Sagittaria subulata is a classic choice for beginners due to its hardiness and adaptability. Its carpet-forming ability makes it perfect for creating lush, natural aquascapes in both small and large tanks, and it provides excellent shelter for fish fry and shrimp.
