Thanks for the replies!
I started off just cutting a few pieces, and they were pure dried out wood, and then just ended with the stump, being the point of impasse, with me maybe exploring any last-ditch potential opportunities.
It was my first plant, so I'm partial to it, but as a last-ditch alternative, I wish I did have some more seeds that it made. I have chili that has been frozen that has seeds, but I doubt they'd germinate. I wish I would have stored some properly in the refrigerator.
Definitely is moss at the bottom. The picture was taken after I had watered it. I wait until the plant is almost dry, but not completely (usually), but the funny thing is that even when it's at that point where the surface of the soil is dry and the sun has been on it, I can see some difference between the surface of the dead trunk and the near bottom, though it could probably just be moisture. With regard to the top roots, I immediately exposed them like that in the very beginning of the spring, and they've grown huge in diameter, as there's an enormous difference between then and now, with a new growth into the soil (at the same level as the other ones, which were exposed initially). I appreciate you ruling these out though, per Occam's razor, which is good.
All of you have great replies, and it does seem like there would have been a new shoot by now, but I'll give it until fall to see if anything happens. Meanwhile, I'm open to any suggestions or advice on improving my odds. Thanks again
