The Mistletoe Moon is a good name for the full moon of December. Of course there's the Christmas tradition of kissing under the mistletoe, and it is a wintery sort of plant. It gets its white berries in the winter, and if it's growing on a deciduous tree, like this elm here, it's a lot more noticeable in the winter when the host tree drops its leaves and the only leaves you now see are bushes of mistletoe.
I've heard that mistletoe is a lot more common in Texas than it is in Europe (it's also a different species), which is an important thing to keep in mind when thinking about its mythical status. In Europe it's a rare oddity to find a green mistletoe bush on a barren tree in the dead of winter, so I can see how it can seem magical. Here it's mostly considered a pest. I've seen some very heavily infested trees. I've never heard of mistletoe actually killing a tree, though, but I guess it is possible. One redeeming quality is that the berries of mistletoe are an important winter food for birds (along with holly, another Christmas plant). The birds return the favor by spreading its seed to other trees.
I heard the full moon was an eclipse this time, but I missed it because of all the clouds. It's been raining a lot lately. We're actually ahead on rain for the months of November and December, though we're still way behind for the year.
Once again I find myself wishing I had planted more for the winter garden. Winter is a great time to garden in Texas. As long as you plant things that can take the occasional freeze, you can have stuff growing all winter, and you don't have to water nearly as much as you do in the summer. Summer really is the true off-season around here, not winter.
