Sagittaria platyphylla is normally known as Chilensis or Broad Leaf Sagittaria, and is a wide cutting edge, grass-like plant. It is green in color, fast growing and can be set in an assortment of areas inside the aquarium.
Plant the Chilensis in clusters or independently in the mid-ground some portion of the aquarium to provide a variance of leaf styles within the aquarium. Trim any dead tips on these plants, to prevent the whole leaf from rotting.
This plant is amphibious and will grow out of the water in a small aquarium. Provide a moderate amount of light in the range of 2 to 3 watts per gallon, using full spectrum bulbs (5000-7000K).
Propagation with this plant happens through sprinters set out by the plant, or by seed generation. Enable the new plant to build up a root framework and immature leaves prior to isolating it from the mother plant. At that time, it can then be planted in a different area, or just left similarly situated.
The Chilensis profits by consistent increments of CO2, iron rich fertilizers, and trace elements.
