I really love massive old trees, they look so very wise and calm. Everytime I see one, I really have to stop and appreciate it for a few moments. A wedding under a grand old tree is a wonderful idea, and you would hardly need any more decorations, perhaps just lanterns for the evening, but a tree as the one obove is both a special location and perfect decoration at the same time. I recently found a few cool wedding pictures including stunning trees. If my wedding for some reason shouldn't be under a palm tree, an oak tree would happilly do.
