... Mistletoe grows wild around here. It is one of those "traditional" Christmas images that are actually ancient Pagan symbols. Mistletoe fruits at the winter solstice, and like the evergreen tree and the holly, it promises that the world will not remain a cold, lifeless place, and that spring will come again. Mistletoe is described as hemi-parasitic. We first noticed the large spheres it formed in the upper branches of oak trees, but it took us a while to figure out what the spheres were. In Norse Mythology, every living creature was asked to promise not to injure the beloved god Baldr, but the mistletoe was thought to be too puny, or weak, or young, or unimportant to make such a vow. The trickster god Loki got wind of this, and made an arrow (or spear) out of mistletoe. Because Baldr was deemed impervious to harm, the gods amused themselves by throwing dangerous items at him, and laughing at the lack of harm they inflicted. (Don't try this at home, kids!)
