Sagittaria sp. ‘Needle’ | A Slender, Graceful Plant for Soft Aquascape Backdrops

Sagittaria sp. ‘Needle’ is a narrow-leaved aquatic plant, most likely a variation of Sagittaria subulata, with slender, grass-like leaves that are only a few millimetres wide and reach 6–12 inches (15–30 cm) in length. Planted in groups, they form a soft, flowing stand of fine green blades that sway gently with the water movement and bring a delicate, natural quality to a freshwater aquascape.

Easy to grow and forgiving of a wide range of conditions, ‘Needle’ is a good choice for beginners and experienced aquascapers alike. Its compact, upright growth works well as a soft backdrop or a flowing midground feature, and it contrasts nicely with broad-leaved plants and hardscape.

Care at a Glance

• Scientific name: Sagittaria sp. ‘Needle’ (likely a Sagittaria subulata variant)
• Leaf length: 6–12 inches (15–30 cm), only a few millimetres wide
• Growth: Spreads readily by runners
• Light demand: Moderate, and thrives without added CO2
• CO2: Not required
• Best placement: Midground to background, planted in groups

A Touch of Colour

Under intense lighting, the vibrant green foliage may develop subtle orange hues, adding warmth and visual interest to the plant. In moderate light, it keeps a clean, fresh green.

Easy to Propagate

‘Needle’ multiplies on its own by sending out runners, filling in gaps naturally over time. To propagate or thin it, simply trim the runners and replant the new plantlets elsewhere in the tank. A little trimming now and then keeps it tidy and stops it from crowding out slower-growing neighbours.

Planting Tips

Plant in clusters or small groups, spacing individual plants a couple of centimetres apart so the runners have room to spread. Plant in the substrate with the crown (where the leaves meet the roots) sitting at or just above the substrate surface. A nutrient-rich substrate or root tabs encourage strong growth, though it is undemanding and will do well without them.

Compatible With

• All community fish, shrimp, and snails
• Suitable for low-tech and beginner planted tanks, nature-style aquascapes, and shrimp tanks
• Works well alongside broad-leaved plants such as Anubias and Cryptocoryne, where the contrast in leaf shape adds visual interest
