Of the species, Astrophytum capricorne, is one with a more typically cactus-like appearance.
This week my A. capricorne gave me one more reason to appreciate it: It bloomed for the first time.
A. capricorne in flower. This is as open as the flower got. For one thing, I think it would be difficult for it to open wider, as its base was surrounded by a virtual cage of thorns. For another, the weather has been cloudy and a bit rainy for the past couple of days, which can put a damper on cactus flowers.
Fully open or not, it was a lovely flower, quite a bit larger than those I had seen on my Astrophytum asterias. The red and yellow coloration was richer, too.
Actually, I was quite surprised that it flowered at all, as I thought it was still an immature plant. For one thing, it had very few spines when I bought it a few years ago. It has only been in the past year that they've started to look like they mean business. For another, the plant hasn't increased in size very much. It has been in this 2.5 inch pot since I brought it home.
