I do not know the name of this plant, but a terrible thing happened to it. Some creature chewed up all the leaves in a day! I was so shocked to see the leaves gone when I checked out the plants one fine evening. I found the culprit the next morning. A hornworm was wandering in the pot, they are notorious for eating tomato and pepper plants. It was looking for more leaves. Hornworms are these disgusting creatures who can devour plants in a very short time. You know that they exist on your plants by the trail they leave behind (black poo on the ground). Anyway I killed it. I thought I had taken take of them when I removed my tomato plants. Here is the poor plant :( All that's remaining are the stems.
