Micranthemum glomeratus is prized for its ability to form dense mats with its small, light green leaves. Under intensive light, it tends to develop a creeping growth habit, making it suitable for foreground planting in strongly-lit tanks. It is also well-suited for bushy groups in the middle ground of larger tanks or as a background plant in nano aquaria.

Micranthemum glomeratus – The True Pearl Weed for Vibrant Aquascapes

Micranthemum glomeratus, commonly known as Pearl Weed, Baby Tears, or Pearl Grass, is a delicate and fast-growing stem plant originating from Florida. Previously misidentified as Hemianthus micranthemoides or Micranthemum micranthemoides, this species was correctly identified in 2011, and has since earned popularity among aquascapers for its fine, curved light-green leaves and bushy growth form.

This versatile stem plant adapts beautifully to a variety of aquascaping styles—whether used as a foreground carpet, a dense midground bush, or even as a nano tank background. Its small size and responsive growth habits make it a favorite for trimming, shaping, and layering within complex layouts.

WHAT WE CAN'T GUARANTEE

Even though our plants are very clean, but we can't guarantee they will be 100% pest-free because we cannot be responsible for your aquarium. Please use it at your own risk. We recommended all customers rinse the plants with clean water and quarantine them before use.

However, plants in tissue culture will be 100% free from pests, algae and never have been contacting with any aquarium.

  1. Due to the nature of the product. We don't guarantee our plants will be pests free. ( snails, algae, hitchhikers )
