I actually had bought some that will be coming in the mail next week just this morning, and then this afternoon I went out to the saturday market, and what should I find but somebody selling succlents and cacti who had two little pots of lithops!
Well, how could I pass that up? No waiting for them to come in the mail, they were just right there! So I bought one.
After I bought it I noticed that one of the plants was starting a second head, kind of hidden under one of the old leaves. You can just make it out in that photo if you look close. Looks like a happy, healthy plant!
