They look like standard African violets to me. You may see what I mean if you google standard African violets
. They are easier to start from a leaf, they have larger flowers and more of them, and they bloom more frequently. It was only after people began developing newer varieties and trying to make them smaller that difficulties arose. That's why they became know as "difficult" plants. Back in the old days, African violets were considered one of the easiest plants to grow, and almost every home had a few.
Standards are the old-fashioned type of African violets my grandmother grew. They were also the ones I grew when I first became interested in Saintpaulias. They've been around for a long time. I sure wouldn't pay any $30 for one, either. Lately, however, the old standards have been a bit harder to find than the fancier named varieties, which may be why this company decided to create a special name for them and tell a story about them being sent out into space.
I'm not saying a plant wasn't
sent out into space, I just doubt it would have been enough to create a dramatically different strain of plants. But that's just my opinion.
The care they suggest isn't different from what is recommended for all African violets. I don't use any special watering device or pot, either. I just submerge the pot up to the rim and wait for the water to show on the surface of the soil. Works for me. Worked for my grandmother, too.
I apologize if I seem to be a wet blanket. If you want to buy one of these violets, by all means do so. It's always a good thing to enlarge one's collection of plants, especially with ones you enjoy.
Here is a page of pictures of standard African violet varieties that you may enjoy. I plan to order a few soon, I think.
