Dwarf Sag (Sagittaria subulata)
Dwarf Sagittaria is a fast-growing, grass-like plant that forms a vibrant green carpet under the right conditions. Though called "dwarf," its height can vary based on lighting—staying low and compact under high light, or growing taller in shaded tanks. It spreads quickly by runners and is a popular choice for both foreground and midground planting.
