Sagittaria graminea

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Suitable for the midground or background depending on the size of the aquarium. It looks best when planted in groups to form a dense stand. It can also be used to create a grassy transition area between foreground and background.

Botanical form

runner

Features long, strap-like green leaves that resemble thick grass blades. In its submerged form, the leaves are typically flexible and slightly translucent. It may produce small white flowers if it reaches the water surface or is grown emersed.

Growth

Medium

Grows at a moderate to fast pace, especially when provided with strong light and a rich substrate. It sends out runners to spread across the aquarium floor. Growth slows significantly in low-light environments.

Substrate

High

Column fertilization

Recommended

Can absorb nutrients from the water column, but is primarily a root feeder. Liquid fertilization is helpful in tanks with inert substrates. Occasional dosing of iron and trace elements supports healthy green coloration.

Root fertilization

None

Thrives when provided with a nutrient-rich substrate or root tabs. A strong root system is essential for its vigorous growth and runner production. Active soils are ideal for encouraging a lush, dense patch.

Trimming

Occasional

Maintenance is simple; remove older, decaying outer leaves by pinching them off at the base. To control its spread, trim the runners periodically. Do not cut the leaves across the middle, as they will rot down to the base.

Propagation

Runners

Propagates prolifically through runners (stolons) that sprout new plantlets. Once a plantlet has developed its own roots and leaves, the runner can be cut. The new plant can then be moved or left to expand the group.

Sensitivity

Moderate

A hardy and adaptable plant, tolerant of various water parameters and lighting conditions. It is relatively resistant to algae unless the leaves begin to degrade. A great choice for beginners due to its undemanding nature.

Layout role

Midground, Foreground

Functions well as a grassy background in smaller tanks or a midground accent in larger setups. Its simple, linear leaves provide a natural, calming effect. Useful for adding vertical lines and a sense of height to the aquascape.
