Christmas moss

It has a very special, fine-grained structure that resembles the crown of a fir tree, hence its name Christmas moss. It is more difficult to grow than classic Java moss and it grows gently. You can easily attach it to wood or stone, where it will stick. When it grows upwards, you will need to prune it. Or otherwise you will not be able to see the beautiful structure of the fir trees. It will just become a mass of foam.
