Paul, those are some gorgeous African violets!
You have a lot of them, too--wow!
I only have three, but I'm happy with how they have grown in the last year. Atleast two of mine look like varieties you have. All the of mine are just common, unnamed varieties from chain stores. The purple/white one was my first, purchased from a small chain of grocery stores that no longer exists. The deep purple and deep magenta African violets came from Walmart.
