Marimo Moss Balls
Not actually moss but a species of algae (Aegagropila linnaei). Grows naturally in Icelandic and Japanese lakes.
Size: pea to softball. Grow 5mm per year. Can live 100+ years.
Marimo Care
Tap water OK, room temperature, low to medium light. Roll weekly to maintain spherical shape.
Too bright or warm light turns them brown. Move to cooler, shadier spot.
Wabi-Kusa Creation
Wabi-kusa is a plant ball — collection of aquatic plants growing on a compact soil ball above water level.
Mix aquarium soil + peat + keto (Japanese clay). Shape into ball. Plant stems, moss, and ferns. Water mist daily.
Display Ideas
Moss balls in bowls with betta or shrimp. Wabi-kusa in open-top jars or rimless tanks. Both need minimal water.
Gift-worthy, aquascape-friendly, and ultra-low maintenance. Perfect for office desks.
