Flowers from last Summer.
Wonderful flowers Alain. What's the second one down from the top? I like the long dark spines on that plant, and I don't remember seeing so much wool on a Thelo. I have several nice plants of T. setispinus, but my labels still say, "Hamatocactus setispinus". I'm just slow to change. :)
The second one down is rinconensis. It does have a lot of wool which contrasts well with the spines. If you wait long enough they will probably become Hamatocactus again.
