Beth, I finally found a link to DG where that plant is pictured with lots of missing data. I clicked on the website to the one vender listed Peppers Greenhouses. This is what I found listed on their online catalog: A cucurbet (misspelled) vine from Burma with lance shaped leaves in sets of 3 produces big clusters of small straw colored flowers..let dry between waterings. I don't know how reliable his descriptions are, but I do know that his reviews on DG Plantscout are terrible. Here is what I originally intended to post:
Treehugger, did you check out the link above that I posted? Looking at your last picture, your plant has all of the qualities of a watermelon peperomia. It does look a lot like the last once pictured, the NOID, which sounds a lot like the descriptions of peperomia japonica. People sometimes make names up just to get unsuspecting buyers to purchase from them. JMHO.
