Sagittaria subulata

Subulata is a thin, grasslike looking plant. The leaves are green in coloration with some areas of reddish brown. A "dwarf" variant is often available as well as the "regular" Subulata but height is often dependent on lighting; the plants will grow taller in lower lighting but will stay more compact and spread laterally in higher lighting. They will reproduce by sending out runners with new little plants that can be separated from the parent or left to spread on their own. Subulata may tolerate brackish water environments with very low salinity or lower light conditions but will grow best in softer water and under high light.

Sagittaria plants are popular "grassy" plants. They are often confused with the "Val's" from genus Vallisneria, but Sagittaria's typically have stiffer blades while the Val's are usually more delicate and flowing. Sagittaria plants spread by extending "runners" with new small plants from the larger plants. They benefit from mineral and nutrient supplements like iron and CO2.
