Overview
Ammannia gracilis is a large stem plant from West Africa. Its leaves are long, narrow and pointed; they are arranged in opposite pairs and curve slightly downward. In strong light and with good nutrition, the leaves take on warm tones from orange-red to pinkish brown. With its broad leaves and tall height, it looks best in the background of aquariums of 80 liters or more. It survives in medium light, but stays greenish-brown and may drop its lower leaves.
Planting and Placement
- Stems are planted one by one, with 4–5 cm between them, 3–4 cm deep; the broad leaves should not be crowded.
- It is used in the background as a color focal point in front of or among green plants.
Care and Fertilization
- Light: High.
- CO₂: Not required, but clearly beneficial for color and growth.
- Fertilizer: Iron and potassium supplementation; a nutrient-rich substrate and root tabs are recommended.
- Trimming: Cut from the top; the cut tops are replanted.
