Some gardeners hate it – others gardeners, like me, cannot get enough of it. What am I talking about? Moss. Moss is a simple little plant that does not have conventional roots, stems, or leaves. Moss is any species of the class ‘Bryopsida’ and is part of the division ‘Bryophyta’. ‘Bryophyta’ means the first green land plants to develop during the evolutionary process. Moss is thought to have evolved from very primitive vascular plants. Dinosaurs may have munched their way through tons of it and it has been used by gardeners in ancient cities to supply the backdrop to many beautiful gardens, perhaps even in the ‘Hanging Gardens of Babylon’.
It is interesting that moss has not given rise to any other kind of plant.
