Sagittaria subulata ‘Needle Leaf’ is a highly versatile, beginner-friendly aquatic plant renowned for its ultra-narrow, grass-like leaves that create a soft, meadow-like look in freshwater aquariums. It serves as an excellent, low-maintenance alternative to Vallisneria nana.

Plant Overview:

• Scientific Name: Sagittaria subulata ‘Needle Leaf’
• Growth Rate: Medium to Fast
• Height: 15–30 cm
• Leaf Width: Only a few millimetres wide
• Placement: Foreground (large tanks), Midground, or Background (nano tanks)
• Propagation: Spreads readily via underground runners

Key Features & Aesthetics:

• Delicate Appearance: Compared to standard Dwarf Sagittaria, the ‘Needle Leaf’ variant features significantly thinner, lighter, and more elegant foliage.
• Colour Shifting: While primarily vibrant green, the leaf tips can develop subtle, attractive orange hues when exposed to high-intensity lighting.
• Unpredictable Height: Like many Sagittaria species, its height varies. Stronger lighting usually forces it into a shorter, more compact carpet, while low light causes leaves to stretch upward toward the surface.

Care and Water Parameters:

• Temperature: 18°C – 28°C
• pH Level: 5.0 – 8.0 (prefers 6.5 – 7.5)
• Lighting: Low to High (Moderate is ideal)
• CO₂ Demand: Low (Not required, but accelerates growth)
• Substrate: Prefers nutrient-rich soil/gravel or root tab supplementation

Planting and Maintenance Tips:

• Tissue Culture Preparation: If you purchase this plant in an in-vitro / tissue culture cup, thoroughly rinse the nutrient gel from the roots with lukewarm water before planting.
• Spacing: Separate the clump into smaller sections and plant them a few centimetres apart into the substrate. This allows space for runners to fill in the gaps naturally.
• Handling the “Melt”: Do not panic if some leaves melt, turn yellow, or fall away within the first week. This is a normal transition phase as the plant adapts from laboratory or emersed growth to your aquarium’s water. New, submersed leaves will quickly follow.
• Trimming: To keep it looking pristine and control its spread, occasionally snip older leaves at the base or cut runners that enter unwanted areas.
