Echinodorus grisebachii, commonly known as Amazon Sword or Melon Sword, is a popular and widely cultivated species of aquatic plant in the aquarium hobby. Belonging to the Echinodorus genus, this plant is appreciated for its robust nature, large and attractive leaves, and ease of care. Here are key details about Echinodorus grisebachii:
-
Appearance:
- Echinodorus grisebachii typically features large, sword-shaped leaves that can grow to be 12-20 inches (30-50 centimeters) or more in length.
- The leaves are usually green, and the plant may produce a rosette of submerged leaves with long petioles.
-
Growth Habit:
- Amazon Sword plants exhibit a rosette growth habit, with leaves emerging from a central crown. Mature plants may also produce daughter plants through runners.
-
Lighting:
- Echinodorus grisebachii can adapt to a range of lighting conditions but generally prefers moderate to high lighting for optimal growth.
- Adequate lighting is crucial for maintaining the plant's health and promoting the development of lush, green leaves.

- pH: 6.5-7.5
- Hardness: Soft to moderately hard water is generally suitable.
-
Substrate and Planting:
- Provide a nutrient-rich substrate to support the plant's growth, as Amazon Swords absorb nutrients through their roots.
- Plant the roots in the substrate and avoid burying the crown, as this can lead to rotting.
-
Propagation:
- Echinodorus grisebachii can be propagated through the production of runners, which develop into new plantlets.
- To propagate, separate the daughter plants once they have developed a sufficient root system and plant them in the substrate.
-
Compatibility:
- Amazon Sword plants are generally compatible with a variety of aquarium fish and other aquatic plants.
- They can be used in both freshwater and brackish water setups.
-
Maintenance:
- Regular pruning may be necessary to control the size and shape of the plant.
