Lindernia rotundifolia

Lindernia rotundifolia, commonly known as Round-leaved Lindernia, is a species of aquatic plant found in wetlands, shallow ponds, and slow-moving streams throughout tropical and subtropical regions of Asia, Africa, and Australia. It is a popular aquarium plant due to its attractive, round leaves and ease of cultivation.

The leaves of L. rotundifolia are arranged in pairs along the stem and are nearly circular, ranging from 5-15mm in diameter. The plant can grow up to 30cm in height and forms dense mats in shallow water. The stems are thin and delicate, with small, inconspicuous white or light purple flowers appearing on the plant in summer and autumn.

L. rotundifolia is an adaptable aquarium plant that can tolerate a wide range of water conditions, including moderate to high light, and both soft and hard water. It can be grown both emersed and submersed, with the submersed form being the most common in aquariums. In the wild, L. rotundifolia serves as an important food source for waterfowl and other wetland animals.

Due to its hardiness and attractive appearance, L. rotundifolia has become a popular choice for aquascaping enthusiasts and is often used as a foreground or midground plant in planted aquariums. It is also used in wetland restoration projects to improve water quality and provide a habitat for wildlife.
