Correct. I was looking mostly at the flower shape and it's basic color. The ones I have are solid orange the same as the generic orange daylilies I grew up with, and the leaves on my plants have tiny ribs which you can see in my OP and are solid green.
There's nothing slow-growing about the ones I have. They're planted in pure Texas clay and they were frozen all the way down to the ground by our infamous February 2021 Texas cold spell, but by June they were back up to full size like they are in my OP.
BTW the webpage where I got the photo in my reply to NewGig called that flower "
Canna Pretoria Bengal Tiger". It's not an exact match to mine, but pretty close. This photo from a different webpage shows the flower shape better.

And you're right the leaves on this variety are strongly variegated. mine aren't. But now that I have a name I can call them, I'll be able to find a close match.
