Hemianthus micranthemoides, commonly known as Pearlweed, is a graceful aquatic plant native to North America. Its small, arched leaves resemble a miniature version of Egeria, adding delicate texture to freshwater aquariums. Under intense lighting, it exhibits a characteristic trailing growth, making it suitable for foreground placement. In terrariums, it forms a compact cushion. This plant was previously known as Micranthemum micranthemoides.
| Difficulty Level | Advanced |
|---|---|
| Lighting | Medium to high |
| CO₂ Requirement | Medium (6-14 mg/L) |
| Growth Rate | Medium |
| Placement | Foreground to midground |
| Propagation | Stem cuttings; replant trimmed stems into the substrate |
Propagation of Hemianthus micranthemoides is achieved through stem cuttings. Trim healthy stems and replant them into the substrate using aquascaping tweezers. The plant will quickly root and continue growing, allowing for the creation of dense carpets or bushes.
For optimal growth, Hemianthus micranthemoides benefits from CO₂ injection and strong lighting. Under these conditions, it can form dense bushes and produce side shoots that grow slanted or horizontally. Without CO₂ supplementation, the plant may develop lime deposits on its leaves through a process known as biogenous decalcification. Regular trimming is recommended to maintain its shape and prevent overcrowding.
