This is a dwarf Myriophyllum that will keep a more compact growth habit both subersed and emersed. It has a great feathery looks that provides a distinct contrast in texture to many other aquatic/riparian plants available. When growing emersed the stems will only be able to support themselves to a certain height before falling over and growing in a more prostrate or even trailing style. When planted en masse or with a group of other taller plants you can achieve more height.
Difficulty: Medium/Hard, only because this one takes longer to acclimate when emersed. You make see die-back or drying of some of the feathery leaves but new ones will regrow from the central stem. Once this plant is acclimate it can be quite hardy and can even thrive outside of a terrarium.
