Habitat : Limnophila aromatica is native to Southeast Asia, where it flourishes in hot temperatures and grows most often in watery environments, particularly in flooded rice fields. It is called ngò om or ngo in Vietnam and used as an herb and also cultivated for use as an aquarium plant.The plant was introduced to North America in the 1970s due to Vietnamese immigration following the Vietnam War.
Limnophila aromatica grows to a height of 10 to 20 inches (up to 24in.) (MID to BACKGROUND) The width of each stem is about 2 inches, based on leaf growth
Medium to high lighting (2.0 – 4 watts/gal) Optimum growth temperature is 72 to 82.4 degrees
There are several varieties of this plant. The variety grown by Tropica is said to come from Malaysia. It is characterised by its narrow green leaves, which are purple underneath. Like most other red plants, the colour depends on a supply of intensive light. CO2 addition promotes growth significantly, and it also thrives in hard water. Limnophila aromatica is easy to propagate by cuttings. (Excerpt From Tropica)
Limnophila aromatica grows best on drained but still wet sandy soil of harvested rice paddies for a few months after the rainy season ended. After rain stops at the end of monsoon reason in Cambodia, on the right soil, the herb grows everywhere like wildfire. it dies out soon after it flowers. Rural Cambodians often harvest them and put them on the roof of their houses to dry for later use.
