Okay, many of the years while I was growing up, my mom would get trees she wanted to plant in the yard, after Christmas, so we had trees in pots. She got pines 1 or 2 times, we had a plum, and the year I won't forget was the citrus tree she got one year. Orange trees have terrible thorns. She never got a cactus, but this was the only "tree" I had in a pot.
Traditions have changed a bit, and now we have clam chowder every Christmas Eve at my mom's. There aren't any presents, just time to visit together, then to the late candlelight service at church.
