Tall Narrowleaf Sagittaria (Sagittaria subulata) is a grass-like plant with roots and, as its name states, several long, narrow, green leaves. It can be grown emersed or submerged, and it propagates prolifically through runners, plus it can develop an extra stem that will flower just above the surface of the water. This versatile plant can eventually grow to a height of 20 inches (51 cm), so it is ideal as a mid-ground or background plant, depending on the size and height of the aquarium. Tall Narrowleaf Sagittaria can even live in brackish water.
Tall Narrowleaf Sagittaria is one of the easier aquarium plants to maintain. It can thrive in a very wide pH and temperature range. It does not require CO2 supplementation or overly high lighting, but it will look its best and grow fastest with moderate to high light. If kept under high light and nutrient-rich water, it can develop red coloration on its leaves.
You are buying one bunch, three rooted plants.
Only plant the roots, Not the plant itself (where the green starts) in your substrate. Planting this plant too deep can cause it to melt. Adding fertilizer tabs a couple of inches from the roots is suggested.
