Pearl Grass - Hemianthus glomeratus

Pearl Weed (Hemianthus glomeratus) has small rounded leaves on each stalk. It is very similar in appearance to the popular Baby Tears (Micranthemum umbrosum) and used to be referred to as "Micranthemum micranthemoides" or "Hemianthus micranthemoides". When under higher lighting, this plant will spread out as a carpeting foreground plant. Under lower lighting or if very densely planted, it will grow taller and is a suitable midground plant.

Bunched plants are typically sold as cuttings that are bound together with a metal plant weight or rubber bands. These individual stalks can be planted by inserting the end of the stalk into the substrate, either individually or - with some plants - in groupings of several stalks. Most bunch plants do not have roots but may grow roots in time. They can be easily pruned by trimming the stalk at the desired height. The trimmings can then be planted as well if desired. Some bunched plants do not need to be planted and may be allowed to float on the water's surface.
