Pretty sure this one is K. blossfeldiana and certainly what I call a florist Kalanchoe. It was a funeral plant for a neighbor's husband. The widow gave it to my Mother because she had too many plants to take care of at the time. It's been hanging around for more than a couple of decades since. I don't find it terribly appealing, but the hummingbirds do. It usually begins blooming in the winter and always has an etoliated lean by the time it gets moved outside. It's actually looking good right now in spite of that and the hummingbirds found it the first day. Not too much blooming for them right now. Spring is slow this year.
