Micranthemum glomeratum aka Hemianthus glomertum aka Hemianthus micranthemoides is a fast growing plant that displays small, bright green teardrop-shaped leaves along a trailing stem. Also known as Pearl grass or Pearl weed, it will grow upright if stems are planted densely, or in a spreading pattern when planted sparsely. Intense lighting will encourage it to creep along the substrate, and with regular trimming an easy carpet can be formed.
Micranthemum glomeratum is simple to grow, requiring moderate to bright light and regular fertilisation. CO2 is beneficial but not required, making this plant a great choice for low tech aquariums.
