Never seen one, but I can testify that Super 100 hybrid(cherry tomato plants)
can produce 11/2 lbs. per week 2 months at a time. Mine bore fruit 8 months out of 10 first time out. Organic of course! I couldn't give 'em away fast enough. Okra too. Cayenne peppers are prolific producers as well. Banana peppers, jalepenos...I ususally just grow nightshade types. BTW the peppers averaged 4 hrs direct sunlight. Someone else here could enlighten further I'm sure.
