Pearlweed is a common name applied to several different plants, often those with small, pearl-like foliage or flowers. It's frequently used to describe aquatic plants popular in aquariums. These plants create a lush, green carpet effect. They are relatively easy to grow and maintain. They also come from the *Sagina* genus. Think of them as the greenery in an underwater world, providing shelter and beauty. They're like the set designers for your aquarium.
