About Long-lobed arrowhead
Sagittaria longiloba, commonly known as Arrowhead plant, is a perennial aquatic plant featuring long, narrow leaves that emerge from the water, creating an elegant silhouette. Its vibrant green, arrow-shaped leaves provide a beautiful contrast in ponds, aquariums, or water gardens, adding a natural and serene touch. It is ideal for the edges of water bodies or as a background plant in large aquariums, where it can form dense clusters.
Native range
Mexico and the southern United States
Care tips
It requires full to partial sunlight and prefers a nutrient-rich substrate, preferably muddy or clayey at the bottom of the pond or aquarium. Maintain a consistent water level, as it is an aquatic plant that thrives submerged or with its roots in water. Avoid substrate dryness, which is the most common mistake, ensuring its roots are always moist or submerged. It is hardy and relatively easy to care for once established.
