Check out this site's pix http://www.bryophyllum.com/b/articles/id/
...the Bryo. daigremontianum & B. 'Houghton's Hybrid'. Compare your plant leaves to those pix. Check the leaf edge near the petiole (stem). See the differences? See the flat, flipped up part on daigremontianum? Then you'll know which is yours.
K. houghtonii is recently (re)named-so there won't be many pix on the web with it. Coloring will vary with sun exposure (and watering habits). I have plenty of pix to share with you once you're postin gon TGF.

Thanks for the name, but the reason I went with daigremontiana is because of the red/pink on the babies as well as the upper leaves. I couldn't find many pictures of the houghtonii, but the few I saw seemed to lack any reddish coloration. I hope not, but it may loose those colors as it grows, maybe? :)

This is Kalanchoe houghtonii, previously Bryophyllum 'Houghton's Hybrid'.
