Redwoods have a number of endearing habits, which to them are processes of survival but to us can appear somewhat magical. Take, for instance, these two trees to the left, which grew so close together that they have begun to overlap at the bottom. Some find the sight romantic; there are a pair of such trees in Sequoia National Park they call "the lovers."

In other cases redwoods will form tree circles. When one tree is injured, it will send out a shoot so a new tree will grow. Eventually the older tree will surround itself with these younger "children," and when the original tree finally dies, its remains nourish the other trees which have grown in a circle around it.
