Tee ~ I love your Manfreda... do you know which one you have? I found a wild one here, Manfreda virginica. It was ID'd when it bloomed. The blooms are the smallest and ugliest but ever so fragrant. It is planted in the raised succulent bed. I harvested seed from the last blooms but haven't attempted germinating them.
BTW, the Caralluma I mentioned earlier is now renamed one of the Orbeopsis or Orbeas if I recall correctly. It is similar to the Stapelias but for me a bit of a struggle. There is a fine balance of winter temps and moisture and I have lost more than one sadly.
It looks like FixPix has a huge selection of plant photos posted on the link. I started looking this a.m. but had to leave for work. I need to go back and look again.
