The Quill-Leaved Arrowhead (Sagittaria teres) is a unique and graceful aquatic perennial prized for its slender, cylindrical, quill-like bright green leaves. Forming attractive focal clusters or textured midground accents, it adds a distinct natural dimension to freshwater planted aquariums and aquascapes.

Short Description & Highlights

Detailed Beginner Care Guide

1. Placement & Aquascaping

Sagittaria teres functions best when planted in the midground of the aquarium, where its unique upright, quill-like leaves can break up hardscape lines or complement darker driftwood and rocks. Space individual stems slightly apart during planting to allow adequate light penetration and give horizontal runners room to expand naturally.

2. Substrate & Root Nutrition

Because this species absorbs the vast majority of its core nutrients through an extensive root system, a nutrient-dense substrate such as specialized aquasoil or fine aquarium gravel supplemented with root tabs is highly recommended. Ensure the crown of the plant sits right at or slightly above the substrate surface to prevent crown rot.

3. Lighting & Maintenance

This plant thrives under low-to-moderate illumination. While it does not strictly require pressurized carbon dioxide (CO2) injection, a balanced liquid fertilizer routine containing iron and micronutrients will ensure lush, vibrant green foliage. Routine maintenance involves trimming older or overgrown leaf tips and managing stray runners to keep your layout neat.
