We added three new succulents to our windowsill garden. One is a living stone, one is an echeveria, and I can't remember the other :) The echeveria has a few flowers so I am going to try and propagate them! I haven't tried this before, but I found a few websites with great instructions.
Succulents are the one plant that I haven't killed yet. Or, almost killed and revived, because I have done that a lot too. They are very easy to grow!
