As I live in a xerophilic zone, I am accustomed to cacti of all varieties and sizes, @velimir. They grow wild all over my city! There are some that bloom and their flowers are so beautiful. It is said that cactus are like some people who cover themselves with thorns so that they are not damaged by the environment that surrounds them and according to Feng Shui, it is good to give cactus to people because you are giving them peace and strength. I send you many cactus for you! Hugs
