The flowers are very nice. Love the color. I've never grown Trichodiadema but I've been ask many time to identify it, usually with the question, "What cactus is this? :)I'm putting together a talk for the Washington DC cactus society on plant identification, may I use one of the trichodiadema photos? As always, thanks for sharing your wonderful plants with us.
Yes very cactus like. More than some Astrophytums. I wonder how long a caudex takes to develop. Please use a photo.
