is a species widespread in a large area covering the majority of
northern Europe. The plants are characterized by slender structure,
medium-big size capitula, with a prominent apical meristem (only
during winter). The colour stays bright green even under direct
sunlight conditions. It tolerates well low humidity and temperature
periods, and it can grow very rapidly forming a compact surface. It
is well-suited for growing in terrariums and ponds to create a
“scenery”. This species is suitable for cold and humid climates.
