Oak- They grow acorns and spirally arranged leaves.
Shrubs-They develop dense frotage.They are disguised by a tree by their height and multiple stems.
Perennial Herbs- They grow and develop during the summer and die in the winter.
Moss-They grow into dense clumps or mats.They are small flower less plants.
My idea is a bedsheets out of moss. Because the moss is dense, I think if it was cleaned up, it would make a great moss bedsheet.
