Heres some pics, before a really long wait until the moss takes over. I have collected 3 different types of mosses around my town.
This is an overall look of the piece of driftwood bare.
Covered by Sphagnum moss, fir bark, and twine to hold it down till moss and eventually roots take care of that...
View of the planting area.
Front view
And kinda of side view.
I plan on having this mound against a wall on a porch or something so that it doesn't get sun really.
I will also have lithophytic ferns and other plants crawling up the neck of the piece to give it somemore green up top.
