Dwarf Baby Tears (Micranthemum umbrosum) – Live Freshwater Aquarium Plant
Scientific Name: Micranthemum umbrosum
Common Name: Dwarf Baby Tears, Giant Baby Tears
Micranthemum umbrosum is a popular freshwater aquarium plant valued for its small, bright-green leaves and tidy growth habit. While often confused with true carpeting plants, this species is best used as a low-growing foreground or midground stem plant, where it creates a lush, natural look when planted densely and trimmed regularly.
Its adaptable nature and attractive leaf structure make it a favorite for aquascapers looking to add softness and texture without aggressive spreading.
