Limnophila (Limnophila aromatica)

Description

Limnophila aromatica (synonym: Limnophila chinensis var. aromatica; also called rice paddy herb) is a tropical flowering plant in the plantain family, Plantaginaceae. It 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 ôm or ngò om or ng? 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. It is called "ma om" (????) in Khmer. It is used in traditional Cambodian soup dishes and Southern Vietnamese cuisine. It can grow in flooded rice paddies during wet season but it grows best on drained but still wet sandy soil of harvested rice paddies for a few months after the rainy season ended. 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.
