I used to have a TON of cactuses when we had a big balcony with space for them, I absolutely love cacti, they are so cool. I actually had many that were either the same or very similar to the ones you posted. Cacti here are also everywhere and very cheap, you can get baby ones for like €1 and grow them up into big ones. I had a few that I even found just out in the wild and cultivated into very large plants. I've never seen those glued on flowers that you mentioned, that's just crazy to me! The flowers are the most beautiful part, it's so special when they flower, and sad some people would glue flowers onto them, so silly. Love the post, but now I miss all my cactus babies that I had to give away when we moved.
Then you're a lucky person. Having these beautiful plants at home is a privilege and they give you a lot of joy when flowering.
I'm really sorry my post made you nostalgic 🙂
