Schlumbergera truncata, Zygocactus or more commonly Christmas Cactus

I purchased this plant two years ago during the holiday season from a local hardware store. Within a few days, all the buds fell off. I then did what the salesperson told me, "pretty much ignore it, hardly water, and place where it gets filtered light. Two years later, in March 2015, the plant developed buds and today it bloomed! Better late than never!
