Delicate in appearance, but hardy in nature, Ludwigia Needle Leaf, or Narrow Leaf Ludwigia is a beautiful amphibious plant that will grow either partially or fully submersed. In its fully submersed form, its narrow leaves range in color from dark green to brownish-red. The top of the leaves are typically olive green in color, whereas the undersides are reddish-brown to deep red.
The Ludwigia Needle Leaf makes a good mid-ground plant in the average aquarium, or even placed as a background in the smaller aquarium. They require a high light intensity of 3 to 5 watts per gallon of full spectrum (5000-7000K) light. The vibrancy of this plant depends greatly on the amount of light it receives. When poorly illuminated, the colors will fade.
