Sorry I didn't get back to this when you posted it earlier, Lauren. CBL (Crazy Busy Life) keeps me hoppin'! Glad Colleen returned...to remind me...and I think you have it! My book lists it as a cultivar name, so it'd be written Haworthia 'Resendeana'. The book says it appears to be a cultivar of H. coarctata & is often written incorrectly as a species.

Normal growth on your plant.

Yes, it looks quite tall. So Cleo is more likely. But I see that there has been a name mix-up, so that plants sold as Cleo are actually Miss Jessie. And Cleo is actually identified as orange in the AHS database. What a mess! There's a discussion here: http://forums.gardenweb.com/discussions/1855411/daylilies-that-look-alike-and-got-mixed-up People who want IDs should note height of plant and blooming period. It's often very difficult to identify something from one picture, though in this case, the picture seems representative.

Not 100% sure about exact ID, but they are Kalanchoes. Most, if not all, will easily grow from leaves, and some have way too many 'babies' (very fitting name for one of them = Mother of millions...)
