I remember Christmas trees lit by candles. The trees were really fresh, usually just dug up, but occasionally sawn down. If they still had their roots they were planted outdoors again when the season was over. Even though I wouldn't put candles on a tree, neither do I like electric lights on them. They just seem so garish by comparison. Having a few candles in the room with the tree or a small light in another room provides enough light to cause shiny ornaments to glow by reflection. It's the scent of the greenery that matters. I'd rather have one bough or even sprig than an artificial tree.
