How to differentiate common types of succulents. All these plant groups are very diverse, however, so it can be difficult to identify these with 100% certainty. However, the guidelines I discuss can usually point you in the right direction.
I didn't mention sedums in this video because, as far as I can tell, there's no way to visually identify them. Sometimes they can look like echeverias, like clover, like graptopetalums, or like strange alien plants that don't resemble anything else. Sedums are a very common kind of succulent, however, so it's good to know that they exist. (Upon further reflection, the unidentified plant in this video is probably some sort of sedum. I'll update this if I find out what it is.)
