My track record as a champion house plant killer notwithstanding, this little plant has survived here for over a half century. Another plant of this species was among the first items I photographed with my then new Kodak Retina Reflex camera. Those slides were processed in January 1964. Other images in that box include several of Scrapper (the family dog), a mata-mata turtle, Vipera ammodytes, and two Christmas scenes. I'll try to scan those slides and add them to this post later.
The Huernia blooms now and then, and every few years I break it up and repot the pieces.
Huernia look like cactuses, but they are asclepiads, related to the milkweeds. As the specific epithet suggests, this species is from Kenya in Africa.
