I know this one! I just got mine at the Phily Flower Show. It's Kalanchoe kewensis, 'Harpoon Leaf Kalanchoe." The leaf form is pinnatisect, which gives them that nifty harpoon teeth. It's considered a hybrid of teretifolia x flammea, was created in 1900 by the Royal Botanical Gardens (hence the species name kewensis, for Kew Gardens). Kewensis is a subshrub (eventually) with bright pink flowers; want bright, indirect light and porous soil. Good for a container, keeps a neat habit. There's also another kalanchoe called Lace Leaf that has multiple "side harpoon teeth." Best of luck with it. Love mine!

Hi mstrgrdnr1, great info, never thought I'd be able to get the name, much less such complete background info!
Thanks so very much!

Great information, I was just was going to say it was any Kleinia that I have ever seen,

Yes, the labels must have been switched or incorrectly placed in the pots. Thanks to this forum the mystery is solved.
