This is a mystery volunteer RL indeterminate that looks like it is producing a cocktail sized beefsteak-shaped fruits in clusters. This first fruit -- maybe 1.75 inches in diameter -- looks like it wants to be white/yellow bi-color with a bit of green shoulder/striping going on. I don't know what variety it could be. According to last year's map, there had been a plant grown from seeds of 2015 Not Mikado White (clear epi yellow/red flesh bi-color) here that didn't grow well and was overwhelmed by weeds and the TKKx pumpkin vine. But it there had been some kind of fruit, this plant might be its off-spring, opening up an exciting possibility that this might possibly be a Not Mikado White PL Bi-color VGSIP'2015 x Champagne Cherry VGSIP'2015
...when I was positioning to take an overall photo, I noticed the missing foliage at the top-left of the plant and immediately thought HORNWORM! So I started looking after taking the photos, and sure enough!
