...and a "Still leben with flowering succulent and root ball."
I used to collect cactus when I was a teenager. I had more than fifty different species. The flowerings were often impressing. I think I lost the interest because of all the stings they gave me. But I still have a few.
This is the first time I see this one flower. (I'm sorry, I don't know the name of it. -If you asked me that twenty years ago, I could have given you any latin name of my cactus, but now... )
