Hi - it is a kalanchoe daigremontianum-- mother of millions aka mother of thousands.
Hope this helps!.
I agree that it is not the diagremontiana....I was too quick to answer --- however, I don't think it is the x houghtonii either --- but rather the delagoensis --- due to the difference where the leaf meets the stem.
Anyhow, I'm certain that I lack experience in these details, so this is as close as I can come. anapatty83 is more than
likely the more informed so I would go with her responsse.
