A Chanukah Bush? Not so far fetched.

Yeah, Chanuka isn't the "Jewish Christmas," but there's justification in traditional sources that says that decoratign with greenery and even a {{gasp}} Chanukka Bush, might be kosher, after all. From the Second book of the Maccabees, chapter 10:

5: It happened that on the same day on which the sanctuary had been profaned by the foreigners, the purification of the sanctuary took place, that is, on the twenty-fifth day of the same month, which was Chislev.
6: And they celebrated it for eight days with rejoicing, in the manner of the feast of booths, remembering how not long before, during the feast of booths, they had been wandering in the mountains and caves like wild animals.
7: Therefore bearing ivy-wreathed wands and beautiful branches and also fronds of palm, they offered hymns of thanksgiving to him who had given success to the purifying of his own holy place.
8: They decreed by public ordinance and vote that the whole nation of the Jews should observe these days every year.
