Sagittaria subulata: A Hardy and Versatile Aquarium Plant

The Sagittaria subulata, also known as Dwarf Sagittaria, is a popular and beginner-friendly aquatic plant. Known for its grass-like appearance and easy growth, this plant is perfect for aquarists looking to create lush carpets or natural midground coverage in freshwater aquariums.

Appearance

Sagittaria subulata features long, narrow, ribbon-like green leaves that grow in rosette formations.

When thriving, it may even send up small white flowers if allowed to reach the surface.
