Sagittaria subulata "Needle"

Species description

Care, breeding and tankmates

Plant profile

Placement

Foreground

Ideal for the foreground or midground where a fine, grassy texture is desired. Plant small groups slightly apart to let them fill in via runners. It looks particularly striking when grown around the base of rocks or driftwood.

Botanical form

Rosette

Distinctive for its very narrow, almost needle-like green leaves that form small rosettes. It has a much finer texture than the standard S. subulata. The delicate leaves sway gently in the water current, adding a sense of motion.

Growth

Medium

Grows moderately fast, spreading through the substrate with runners. It tends to stay relatively short, maintaining a compact, carpet-like appearance under good light. In lower light conditions, it may stretch slightly upwards.

Substrate

High

Column fertilization

Recommended

Benefits from light water column fertilization, particularly in setups with inert substrates. Occasional dosing of trace elements and iron keeps the foliage vibrant. It is less demanding of liquid fertilizers compared to stem plants.

Root fertilization

None

A root-heavy feeder that significantly benefits from a rich substrate like aquasoil or root tabs. Providing nutrients at the roots encourages strong runner production and a denser carpet. It establishes a surprisingly deep root network.

Trimming

Occasional

Pruning is minimal and mainly involves managing its spread. Snip runners that encroach on areas where they are not wanted. Remove any yellowing or dead outer leaves at the base to maintain a tidy appearance.

Propagation

Runners

Propagates easily and continually through runners. It will naturally form a dense, grassy patch over time. You can easily separate and replant runners to start new patches elsewhere in the tank.

Sensitivity

Moderate

A hardy and resilient variant that tolerates a wide range of water parameters. It is less prone to sudden die-offs and adapts easily to new environments. A great choice for aquarists looking for a fine-textured foreground plant that is easy to care for.

Layout role

group, Foreground, Midground, Nano

Excellent for creating a very fine, lawn-like effect in the foreground. Its delicate appearance contrasts nicely with broader-leaved plants and coarse hardscape. It provides a natural, soft transition from the front glass to the midground.
