Hello, I recently bought a cactus container garden from a local store. I recognize two of the species of cacti in this container (Parodia Leninghausii, and Myrtillocactus geometrizans I believe). It is also possible that the cactus in the top left of the container is Stenocereus Pruinosis, and that the cactus in the center is some sort of pincushion cactus (because it has spikes that are curved liked hooks). However, I am unsure of what the other cacti in this container are, and I would like to know. I would appreciate help in identifying the other cacti.
