Dwarf Sagittaria care guide
Dwarf Sagittaria (Sagittaria subulata var. pusilla) — medium light, 18-28 °C, pH 6-8, no CO2.
Overview
Dwarf Sagittaria (Sagittaria subulata var. pusilla) is an aquatic plant of the family Alismataceae, listed in the Aquairi knowledge base as a beginner-level species. It is typically grown under medium light and without obligatory CO2 injection on nutrient-rich aquasoil. Dwarf form of Sagittaria subulata that stays under 10 cm. Forms a fast carpet via runners; adapts to wide light conditions but compacts more under high light.
Taxonomy
- Family: Alismataceae
- Genus: Sagittaria
- Scientific name: Sagittaria subulata var. pusilla
- Common synonyms: Sagittaria pusilla
Habitat
Sagittaria is a genus of arrowheads (Alismataceae) of ponds, ditches and slow streams across the Americas and beyond; dwarf submersed forms resemble short grass. In the Aquairi knowledge base, populations associated with this form are recorded from North America.
Growth requirements
- Lighting: medium
- CO2: not required
- Temperature: 18-28 °C (64-82 °F)
- pH: 6-8
- GH: 4-16 °dGH
- Substrate: nutrient-rich aquasoil
- Maximum height: 10 cm
- Growth rate: fast
- Recommended placement: foreground carpet
Placement
A foreground-to-midground rosette planted in clusters; bright light keeps the strap leaves short, while shade encourages taller emergent growth. In the Aquairi knowledge base this form is recommended for the foreground as a carpet under medium light and without obligatory CO2 injection, using nutrient-rich aquasoil.
Propagation
Spreads by runners that produce daughter rosettes on the substrate; the lawn thickens once runners knit together. Documented propagation techniques for this entry include: horizontal runners.
Common issues
Tall, stretched leaves indicate low light; melting after transplanting is common and resolves as submersed leaves regrow under stable conditions.
