Tissue culture aquarium plant in a sealed cup.

A Brazilian specialty, this moss grows to a height of 1 to 3 cm. It is also called "Christmas Moss" because, unlike common Vesicularia dubyana, its lateral stems are covered with dense strands, giving them the appearance of fir branches.
It is more demanding than ordinary Java moss and grows more slowly. However, it easily attaches itself to roots and stones. It spreads gradually in water and should be trimmed to maintain its beauty and health.
