These were all 2 to 3 inch pot size succulent cactus or whatever else they are called. Very interesting things to observed are that as soon as they are transferred to larger pots, over several hours, the cactus grew in sizes and shapes like they are stretching out their arms.
The little creamy-white flowers on this "Ladyfinger"cactus are real. They shoot out its flower stem carefully of their fine nets of thorns surrounding itself and opens up after peeking out them.
The one to the right is the Cereus Ming Thing Cactus. I am not confident with the names, but if you know, please let me know. It's a gnarly green mound of cactus.
