Lysimachia parvifolia (Samolus parviflorus red)

Lysimachia parvifolia is a beautiful and versatile stem plant known for its small, rounded leaves and vibrant green foliage. Its compact growth and delicate texture make it an excellent choice for adding depth and contrast to planted aquariums. Under high lighting, the upper leaves may develop attractive golden, bronze, or reddish hues, creating even more visual interest.

This easy-to-grow plant thrives in a variety of aquarium conditions and responds well to regular trimming, producing dense, bushy growth that is perfect for the midground or background. Its fast growth also helps absorb excess nutrients, contributing to improved water quality and helping reduce algae.
