Cephalocereus senilis

Seedlings of the Old Man of Mexico used to be very common at the local nursery. The problem was always getting them past that "I'm going to turn to mush on you" stage. That's a stage that came rather regularly in our early years of getting to know succulent plants. Now they're not as commonly available - due, I understand, to a shortage of seed. So if you happen on a nice specimen, you might want to grab onto it...not literally, of course. After all, under all that hair there are some sharp little spines. Kind of like some people I know... And, please,  they don't need little plastic eyes or strawflowers glued onto them!
