Love this plant

My mom had a couple of these cactus all the while I was growing up and they consistently bloomed around Thanksgiving or Christmas. She put them outside in the spring, in the shade, and brought them back in the house in the fall. I have had this one for several years and I am lazy and don't move it at all. But it still consistently blooms around this time every year. 

And added feature is the highlighted raindrops on the window because of the flash.
