This little guy (Crassula "Baby Necklace") is similar to the rupestris, and it seems their names are interchangeable.(Below) I'm not sure of the name of this one, although Mark said it is about 7-8 years old. I really love the woody stem and the beautiful colorful leaves. This has to be my favorite of the four I got today.
Below is the crassula coulmnnella. You can see on the right there are actually two "branches" starting to grow from the center.
These are Mouse Melons. Just one example of the really neat produce Chris and Mark grow. They taste just like a cucumber but with a tangy lime flavor. There was also some teeny-tiny cherry tomatoes on the vine, and last year they had purple tomatillos!
