OAKS ARE THE GNOMES' FAVOURITE TREES and they delight in planting new ones for future generations, often carrying an acorn miles to the right spot and carefully tending the young tree till it is tall and strong enough to fend for itself. The Oak is the king of all trees they will tell you, because it is home to more creatures than any other. It is also the most common host of mistletoe, which the gnomes use for a number of potent elixirs and medicines. In humans mistletoe (in the right measure) is a valuable remedy for nervousness and stress, but gnomes don't suffer much from either and generally use it just to cheer themselves up even more. They also say it keeps them immune from many of the illnesses that afflict us, and there must be something in this because it is rare to find a gnome who is not in the best of health.
