Walgreens has some cute little "greenhouses" with 6 assorted little succulents right now. I couldn't resist getting one... So what do I have here? (Besides a curious kitty... )
I'm gonna take a stab and say the flatter pastel ones look like 2 graptoverias and the puffy pastel one looks like a pachyphytum or a hybrid of like pachyveria. Haven't a clue with the lighter green one and Marilyn is right about the haworthia.
