That is such a cool flower! I bought something at Roger's Garden's today that might be Hoodia. I have to bring it up to the computer and compare it to photos.
Roger's Gardens is legendary and I can now see why. Quite an interesting selection of plants and the the whole place is nicely laid out. They had some Gasteraloe's I hadn't seen so I bought the most prolific-looking specimens of three to propagate for next year. Oh but it will be dull this winter if growth rates slow.
I also got a very fragrant pink carnation for my collection of very fragrant carnations. They are going to look great all humped together in a bed some day.
Rob and Marcella made terrariums last night. M filled a large footed jar with sand and planted a 6" high baby Saguaro in it. She poked down against the glass to draw sand from higher layers down through a few lower layers. The effect is like chocolate frosting dripping off a cake. I have forgotten what Rob did; something with an egg cup. Oh yes, he took some Conos with my approval, although my approval was reluctant to say the least. I put 3 small plants and a plastic pit bull in a square pot. The pot's surface was divided in a 2x2 grid; each item got one square. The dog's entire square was covered with a layer of beige sand that conceals the dark soil.
I also got a nice small columnar cactus at Roger's that was $12.99 and had a few spires in one pot. I hope it stays this cute. Finding out what it is is going to take a while. All the Cereus-type cacti are pretty similar.
Something interesting another day, I promise.
