The Stenocactus genus is noted for having large numbers of wavy ribs and flat spines, and that is why most collectors have them in their collections. The flowers are secondary. Flower color can vary among the Stenocactus species, but many collectors believe that the S. crispatus flowers, as well as its spination, are the most attractive. The median dorsal stripe can range from pink to purple. The flowers pictured here have one of the darker violet median dorsal stripes.
I almost missed these flowers. They came a few weeks early this year, so I wasn't expecting to find them so soon. Luckily, today was my potted cactus-watering day and I found them. It was a pleasant surprise on a nice spring day.
For more information on this cactus, see a previous post. Since that post, I've learned that this cactus has a common name, the Permanent Wave Cactus. This cactus has so many botanical names to choose from that it really doesn't need another name!
