Looks like Boomer to me. Leaves probably won't get much larger but the plant can grow a lot more and get bushy and/or lanky.

Thanks. I think you are correct with suggesting "Boomer". After posting my query, I came across a photo of "Art Hodes" and then "Pigskin", but while similar, neither was a perfect match for mine. I have pinched out the growing tip in hopes of getting some basal sprouts and a bushier plant.

THAT looks exactly what I bought which was tagged as Art Hodes. McDole explained that Hodes has a floppy leaf, but mine feels almost like onionskin paper... kinda rustly and crisp. I'm thinking more and more mine is Boomer or Salamander than Art Hodes.

Here is a link that might be useful: Hodes? Boomer? Salamander?

It might be Art Hodes. It might also be Begonia Jabberwocky which is a cross Ghertii x Soli-mutata.
